Ettention: building blocks for iterative reconstruction algorithms
Proceedings of Microscopy & Microanalysis 2015
August 2015

Abstract: We present a novel software package for tomographic reconstruction in electron microscopy, named Ettention. The software consists of a set of modular building-blocks for iterative reconstruction algorithms. Ettention simultaneously features (1) a modular, object-oriented software design, (2) optimized access to high-performance computing (HPC) platforms such as graphic processing units (GPU) or many-core architectures like Xeon Phi, and (3) accessibility to microscopy end-users via integration in the IMOD package and user interface. We provide developers with a clean application programming interface (API) that allows for extending the software easily and thus makes it an ideal platform for algorithmic research while hiding most of the technical details of high-performance computing. Several case studies are provided to demonstrate the feasibility of the concept.

Reconstruction Strategies for Combined Tilt- and Focal Series Scanning Transmission Electron Microscopy
Proceedings of Microscopy & Microanalysis 2015
August 2015
accepted

Abstract: The STEM transform was thus formulated as a mathematical model applicable to STEM imaging with a convergent electron beam. It was shown that it is (1) a linear convolution, (2) a generalization of the Ray transform that contains the latter as the special case where the beam convergence semi-angle α→0, and (3) self-adjoint, a result that facilitated a new iterative reconstruction algorithm for TFS based on a matched backprojection, which drastically improved the convergence rate, resulting in 60 times less iterations compared to previous methods. It also solved theoretical concerns about the convergence of the method, which was not guaranteed in the case of an unmatched projection/backprojection pair. This brings the combined tilt- and focal series one more step towards broad applicability by allowing the reconstruction of high resolution tomograms in feasible computation time.

On a novel approach to 3D reconstruction in Cryo Electron Tomography: Progressive Stochastic Reconstruction Technique (PSRT)

accepted

Abstract: Cryo Electron Tomography (cryoET) plays an essential role in Structural Biology, as it is the only technique that allows us to study structure of macromolecular complexes in their close to native environment in-situ. The reconstruction process faces many challenges as the input projections suffer from very low signal-to-noise ratio and limited tilt angle. Moreover, the scanned specimen is larger than the detector, which introduces the interior problem into the reconstruction process. High-resolution protocols such as Subtomogram Averaging (SA) can alleviate some of these limitations; however, in order to be fully automatic they require reconstructions of high quality. Current state-of-the-art methods, such as Weighted Back Projection (WBP) or Simultaneous Iterative Reconstruction Technique (SIRT), deliver reconstructions that often require manual intervention during SA. We present a novel iterative approach to the tomographic reconstruction problem called Progressive Stochastic Reconstruction Technique (PSRT). The method is based on Monte Carlo random walks guided by a sampling strategy similar to the Metropolis-Hastings strategy. PSRT is designed to suit the specific conditions in cryoET - it delivers high-contrast reconstructions without any loss of high-resolution structural information and it implements memory efficient solution to the interior problem. Finally, it can be easily incorporated into a typical SA pipeline, where it significantly improves template-based localization and provides an elegant solution to the region-of-interest reconstruction.

An automated workflow for the biomechanical simulation of a tibia with implant using computed tomography and the finite element method
Computers and Mathematics with Applications,
June 2015
accepted

Abstract: In this study, a fully automated workflow is presented for the biomechanical simulation of bone-implant systems using the example of a fractured tibia. The workflow is based on routinely acquired tomographic data and consists of an automatic segmentation and material assignment, followed by a mesh generation step and, finally, a mechanical simulation using the finite element method (FEM). Because of the high computational costs of the FEM simulations, an adaptive mesh refinement scheme was developed that limits the highest resolution to materials that can take large amounts of mechanical stress. The scheme was analyzed and it was shown that it has no relevant impact on the simulation precision. Thus, a fully automatic, reliable and computationally feasible method to simulate mechanical properties of bone-implant systems was presented, which can be used for numerous applications, ranging from the design of patient-specific implants to surgery preparation and post-surgery implant verification.

Progressive Stochastic Reconstruction Technique (PSRT) for Cryo Electron Tomography
Journal of Structural Biology, 189(3):195-206
March 2015

Abstract: Cryo Electron Tomography (cryoET) plays an essential role in Structural Biology, as it is the only technique that allows to study the structure of large macromolecular complexes in their close to native environment in situ. The reconstruction methods currently in use, such as Weighted Back Projection (WBP) or Simultaneous Iterative Reconstruction Technique (SIRT), deliver noisy and low-contrast reconstructions, which complicates the application of high-resolution protocols, such as Subtomogram Averaging (SA). We propose a Progressive Stochastic Reconstruction Technique (PSRT) – a novel iterative approach to tomographic reconstruction in cryoET based on Monte Carlo random walks guided by Metropolis–Hastings sampling strategy. We design a progressive reconstruction scheme to suit the conditions present in cryoET and apply it successfully to reconstructions of macromolecular complexes from both synthetic and experimental datasets. We show how to integrate PSRT into SA, where it provides an elegant solution to the region-of-interest problem and delivers high-contrast reconstructions that significantly improve template-based localization without any loss of high-resolution structural information. Furthermore, the locality of SA is exploited to design an importance sampling scheme which significantly speeds up the otherwise slow Monte Carlo approach. Finally, we design a new memory efficient solution for the specimen-level interior problem of cryoET, removing all associated artifacts.

Matched Backprojection Operator for Combined Scanning Transmission Electron Microscopy Tilt- and Focal Series
Microscopy & Microanalysis,
January 2015
accepted

Abstract: Combined tilt- and focal series scanning transmission electron microscopy (STEM) is a recently developed method to obtain nanoscale three-dimensional (3D) information of thin specimens. In this study, we formulate the forward projection in this acquisition scheme as a linear operator and prove that it is a generalization of the Ray transform for parallel illumination. We analytically derive the corresponding backprojection operator as the adjoint of the forward projection. We further demonstrate that the matched backprojection operator drastically improves the convergence rate of iterative 3D reconstruction compared to the case where a backprojection based on heuristic weighting is used. In addition, we show that the 3D reconstruction is of better quality.

Target-Specific Refinement of Multigrid Codes
Proceedings of the 4th International Workshop on Domain-Specific Languages and High-Level Frameworks for High Performance Computing (WOLFHPC) , page 52-57.
November 2014

Keywords: multigrid codes; partial evaluation; domain- specific language

Abstract: This paper applies partial evaluation to stage a stencil code Domain-Specific Language (DSL) onto a functional and imperative programming language. Platform-specific primitives such as scheduling or vectorization, and algorithmic variants such as boundary handling are factored out into a library that make up the elements of that DSL. We show how partial evaluation can eliminate all overhead of this separation of concerns and creates code that resembles hand-crafted versions for a particular target platform. We evaluate our technique by implementing a DSL for the V-cycle multigrid iteration. Our approach generates code for AMD and NVIDIA GPUs (via SPIR and NVVM) as well as for CPUs using AVX/AVX2 alike from the same high-level DSL program. First results show that we achieve a speedup of up to 3× on the CPU by vectorizing multigrid components and a speedup of up to 2× on the GPU by merging the computation of multigrid components.

Specialization through Dynamic Staging
Proceedings of the 13th International Conference on Generative Programming: Concepts & Experiences (GPCE) , page 103-112.
September 2014

Keywords: dynamic staging; partial evaluation; code specialization

Abstract: Partial evaluation allows for specialization of program fragments. This can be realized by staging, where one fragment is executed earlier than its surrounding code. However, taking advantage of these capabilities is often a cumbersome endeavor. In this paper, we present a new metaprogramming concept using staging parameters that are first-class citizen entities and define the order of execution of the program. Staging parameters can be used to define MetaML-like quotations, but can also allow stages to be created and resolved dynamically. The programmer can write generic, polyvariant code which can be reused in the context of different stages. We demonstrate how our approach can be used to define and apply domain-specific optimizations. Our implementation of the proposed metaprogramming concept generates code which is on a par with templated C++ code in terms of execution time.

Code Refinement of Stencil Codes
Parallel Processing Letters (PPL), 24(3):1-16

Keywords: stencil codes; partial evaluation; domain-specific language

Abstract: A straightforward implementation of an algorithm in a general-purpose programming language does usually not deliver peak performance: compilers often fail to automatically tune the code for certain hardware peculiarities like memory hierarchy or vector execution units. Manually tuning the code is firstly error-prone as well as time-consuming and secondly taints the code by exposing those peculiarities to the implementation. A popular method to circumvent these problems is to implement the algorithm in a Domain-Specific Language (DSL). A DSL compiler can then automatically tune the code for the target platform. In this paper we show how to embed a DSL for stencil codes in another language. In contrast to prior approaches we only use a single language for this task. Furthermore, we offer explicit control over code refinement in the language itself which is used to specialize stencils for particular scenarios. Our first results show that our specialized programs achieve competitive performance compared to hand-tuned CUDA programs.

Progressive Light Transport Simulation on the GPU: Survey and Improvements
CM Trans. Graph, 33(3):29:1-29:19
May 2014
ISSN: 0730-0301

Keywords: GPU; Global illumination; bidirectional path tracing; high performance; vertex connection and merging

Abstract: Graphics Processing Units (GPUs) recently became general enough to enable implementation of a variety of light transport algorithms. However, the efficiency of these GPU implementations has received relatively little attention in the research literature and no systematic study on the topic exists to date. The goal of our work is to fill this gap. Our main contribution is a comprehensive and in-depth investigation of the efficiency of the GPU implementation of a number of classic as well as more recent progressive light transport simulation algorithms. We present several improvements over the state-of-the-art. In particular, our Light Vertex Cache, a new approach to mapping connections of sub-path vertices in Bidirectional Path Tracing on the GPU, outperforms the existing implementations by 30-60%. We also describe a first GPU implementation of the recently introduced Vertex Connection and Merging algorithm [Georgiev et al. 2012], showing that even relatively complex light transport algorithms can be efficiently mapped on the GPU. With the implementation of many of the state-of-the-art algorithms within a single system at our disposal, we present a unique direct comparison and analysis of their relative performance.

Combined Scanning Transmission Electron Microscopy Tilt- and Focal Series
Microscopy and Microanalysis, :1-13
February 2014

Keywords: STEM, tomography, 3D, focal series, whole cell, nanoparticle, SART, 3D reconstruction, back projection

Abstract: In this study, a combined tilt- and focal series is proposed as a new recording scheme for high-angle annular dark-field scanning transmission electron microscopy (STEM) tomography. Three-dimensional (3D) data were acquired by mechanically tilting the specimen, and recording a through-focal series at each tilt direction. The sample was a whole-mount macrophage cell with embedded gold nanoparticles. The tilt–focal algebraic reconstruction technique (TF-ART) is introduced as a new algorithm to reconstruct tomograms from such combined tilt- and focal series. The feasibility of TF-ART was demonstrated by 3D reconstruction of the experimental 3D data. The results were compared with a conventional STEM tilt series of a similar sample. The combined tilt- and focal series led to smaller “missing wedge” artifacts, and a higher axial resolution than obtained for the STEM tilt series, thus improving on one of the main issues of tilt series-based electron tomography.

Keywords: Web3D, WebGL, XML3D, assets, instancing

Abstract: The Declarative 3D for the Web initiative by the W3C [W3C 2011] connects 3D content to the Web document, intertwining it with other Web technologies known to millions of Web developers. The goal is to make 3D on the Web more accessible compared to low-level APIs such as WebGL. However, all proposals for Declarative 3D for the Web are missing an essential feature: configurable instances of structured 3D models. While instance mechanisms do exist, they all have limited capabilities to configure instances individually. In this paper we present a new approach for configurable instances of 3D models that is integrated into XML3D. Our approach comes with a compact interface, a powerful extension mechanism to handle configurations, and an efficient data structures for efficient instancing. We demonstrate how our instance mechanism simplifies the handling of 3D models in several different application areas, including Virtual Worlds, and provide several performance results for the instancing process.

Abstract: Cryo Electron Tomography (cryoET) plays an essential role in Structural Biology, as it is the only technique that allows to study the structure and intracellular distribution of large macromolecular complexes in their (close to) native environment. A major limitation of cryoET is the highest achievable resolution, currently at around 3 nm, which prevents its application to smaller complexes and in turn to a wider range of important biological questions.

Microtiles: Extracting Building Blocks from Correspondences
Computer Graphics Forum, 31(5):1597-1606
2012

Abstract: In this paper, we develop a theoretical framework for characterizing shapes by building blocks. We address two questions: First, how do shape correspondences induce building blocks? For this, we introduce a new representation for structuring partial symmetries (partial self-correspondences), which we call "microtiles". Starting from input correspondences that form point-wise equivalence relations, microtiles are obtained by grouping connected components of points that share the same set of symmetry transformations. The decomposition is unique, requires no parameters beyond the input correspondences, and encodes the partial symmetries of all subsets of the input. The second question is: What is the class of shapes that can be assembled from these building blocks? Here, we specifically consider r-similarity as correspondence model, i.e., matching of local r-neighborhoods. Our main result is that the microtiles of the partial r-symmetries of an object S can build all objects that are (r+e)-similar to S for any e>0. Again, the construction is unique. Furthermore, we give necessary conditions for a set of assembly rules for the pairwise connection of tiles. We describe a practical algorithm for computing microtile decompositions under rigid motions, a corresponding prototype implementation, and conduct a number of experiments to visualize the structural properties in practice.

Abstract: As interactive 3D graphics has become an integral part of modern Web browsers via the low-level WebGL API, it now becomes apparent that higher-level declarative approaches integrated with HTML5 are needed in order to make 3D graphics broadly and easily accessible to Web developers. A key component of interactive 3D scenes are physics simulations. However, specifying the physics properties required major changes to the scene graph in the past. In this paper, we present a declarative and orthogonal physics annotation framework that nicely separates the generic 3D scene description from its physics properties. The approach is based on the declarative XML3D format as an extension to HTML5, has been implemented as a plug-in that runs in three browsers that support XML3D and is demonstrated with a number of examples and performance evaluations.

Abstract: In dieser Arbeit wird eine Methode zur Darstellung und Generierung von natürlich wirkendem Bewuchs auf besonders großen Arealen und unter Berücksichtigung ökologischer Faktoren vorgestellt. Die Generierung und Visualisierung von Bewuchs ist aufgrund der Komplexität biologischer Systeme und des Detailreichtums von Pflanzenmodellen ein herausforderndes Gebiet der Computergrafik und ermöglicht es, den Realismus von Landschaftsvisualisierungen erheblich zu steigern. Aufbauend auf (Dietrich 2006) wird bei Silva der Bewuchs so generiert, dass die zur Darstellung benötigten Wang-Kacheln und die mit ihnen assoziierten Teilverteilungen wiederverwendet werden können. Dazu wird ein Verfahren vorgestellt, um Poisson Disk Verteilungen mit variablen Radien auf nahtlosen Wang-Kachelmengen ohne rechenintensive globale Optimierung zu erzeugen. Durch die Einbeziehung von Nachbarschaften und frei konfigurierbaren Generierungspipelines können beliebige abiotische und biotische Faktoren bei der Bewuchsgenerierung berücksichtigt werden. Die durch Silva auf Wang-Kacheln erzeugten Pflanzenverteilungen ermöglichen, die darauf aufgebauten beschleunigenden Datenstrukturen bei der Visualisierung wieder zu verwenden. Durch Multi-Level Instancing und eine Schachtelung von Kd-Bäumen ist eine Visualisierung von großen bewachsenen Arealen mit geringen Renderzeiten und geringem Memory foot print von Hunderten Quadratkilometern Größe möglich.

Abstract: Today, there are increasingly more powerful many-core processors (MCPs) that are integrated into stationary and mobile devices, freely programmable and well suited for multimedia processing. However, there are still many obstacles and problems when programming multimedia applications for MCPs. In this paper we show that all these obstacles and problems can be solved by treating a device with an integrated MCP in the same way as a distributed system and using distributed multimedia middleware even for developing locally running applications. This approach completely hides all specific aspects of an MCP while the application can fully exploit the processing power of MCPs in local and even remote devices.

March 2009

Abstract: The computer has become an indispensable tool in modern archeology for measuring, recording, organizing, searching, discussing, and presenting results. Particularly important is the use of realistic and interactive 3D graphics technology: It allows to accurately capture and present the archaeological evidence within its current 3D environment as well as to create 3D models of the historic location itself. Different possible reconstructions can be discussed and compared to the existing evidence within the same model, thus allowing to better evaluate scientific hypotheses. Given such interactive 3D models, we can then apply a multitude of other simulation techniques from computer graphics and other fields (e.g., illumination, acoustic and architectural simulations) to try to recreate the historic reality. Using the Internet, we can interconnect research groups on different locations but also make this data widely available and more accessible to non-experts. In this paper we present the ISReal project together with its first results which allows for dynamically create, large-scale, and physically realistic simulated realities with systematic semantic annotations.
