Representing models of cellular processes or pathways in a graphically rich form facilitates interpretation of biological observations and generation of new hypotheses. Solving biological problems using large pathway datasets requires software that can combine data mapping, querying and visualization as well as providing access to diverse data resources on the Internet. ChiBE is an open source software application that features user-friendly multi-view display, navigation and manipulation of pathway models in BioPAX format. Pathway views are rendered in a feature-rich format, and may be laid out and edited with state-of-the-art visualization methods, including compound or nested structures for visualizing cellular compartments and molecular complexes. Users can easily query and visualize pathways through an integrated Pathway Commons query tool and analyze molecular profiles in pathway context.

In this paper, the variable view imaging system (VVIS) developed to offer flexibility in microscopic observation is applied to microassembly tasks to overcome several problems in normal imaging systems that hindered application of vision-guided micromanipulation techniques such as limited field of view (FOV) and fixed viewing direction. In three representative cases of microassembly, the parts are mated by visual servoing, avoiding FOV problem by combining unit FOV's and occlusion problem by changing the viewing direction to the optimal one. The results demonstrate the superiority and usefulness of the VVIS in various micromanipulation tasks.

This research proposes a method for producing music via visual composition in a computer-game like environment. This is accomplished through the development of artificial intelligence software that applies the visual rules of standard emergent behaviors to the algorithmic arrangement of musical tones. This research presents the proposed system, defining the algorithm and demonstrating its implementation.

The goal of the future terrestrial and mobile digital video broadcasting standards is to combine diversity and spatial multiplexing in order to fully exploit the multiple-input multiple-output (MIMO) channel capacity. Full-rate full-diversity (FR-FD) space-time codes (STC) such as the Golden code, that maximize the rate preserving the diversity gain, are studied for that purpose. Most of them present a high-complexity detection problem which results in a handicap for their hardware implementation. Therefore, we analyze the performance of a sub-optimal full-rate full-diversity 2x2 STC, whose design reduces the complexity of the detection, as an alternative for future MIMO broadcasting TV systems. The assessment of the proposed STC code is carried out over the bit-interleaved coded modulation (BICM) scheme of DVB-T2 system which includes low-density parity check (LDPC) codes for error correction. Finally, soft STC list detection is studied in order to generate soft information for LDPC decoding.

Image-based holographic stereogram rendering methods for holographic video have the attractive properties of moderate computational cost and correct handling of occlusions and translucent objects. These methods are also subject to the criticism that (like other stereograms) they do not present accommodation cues consistent with vergence cues and thus do not make use of one of the significant potential advantages of holographic displays. We present an algorithm for the Diffraction Specific Coherent Panoramagram - a multi-view holographic stereogram with correct accommodation cues, smooth motion parallax, and visually defined centers of parallax. The algorithm is designed to take advantage of parallel and vector processing in off-the-shelf graphics cards using OpenGL with Cg vertex and fragment shaders. We introduce wavefront elements - "wafels" - as a progression of picture element "pixels", directional element "direls", and holographic element "hogels". Wafel apertures emit controllable intensities of light in controllable directions with controllable centers of curvature, providing accommodation cues in addition to disparity and parallax cues. Based on simultaneously captured scene depth information, sets of directed variable wavefronts are created using nonlinear chirps, which allow coherent diffraction of the beam across multiple wafels. We describe an implementation of this algorithm using a commodity graphics card for interactive display on our Mark II holographic video display.

In this paper we present a new technique for non photo-realistic rendering by using genetic programming. Our technique produces aesthetically pleasing animations in which a subject gradually emerges from a random collection of brushstrokes. We employ triangular brushstrokes with three different possibilities of strokes drawing on the canvas. The animations are evaluated by using a numerical measure of similarity to a target image and a qualitative evaluation of aesthetic characteristics by an artist. We provide many facilities to the artists to control the rendered images and create desirable animations.

Ray tracing efficiently models complex illumination effects to improve visual realism in computer graphics. Typical modern GPUs use wide SIMD processing, and have achieved impressive performance for a variety of graphics processing including ray tracing. However, SIMD efficiency can be reduced due to the divergent branching and memory access patterns that are common in ray tracing codes. This paper explores an alternative approach using MIMD processing cores custom-designed for ray tracing. By relaxing the requirement that instruction paths be synchronized as in SIMD, caches and less frequently used area expensive functional units may be more effectively shared. Heavy resource sharing provides significant area savings while still maintaining a high MIMD issue rate from our numerous light-weight cores. This paper explores the design space of this architecture and compares performance to the best reported results for a GPU ray tracer and a parallel ray tracer using general purpose cores. We show an overall performance that is six to ten times higher in a similar die area.

This paper addresses the problem of deploying a group of networked robots on a non-planar surface embedded in 3D space. Two distributed coverage control algorithms are presented that both provide a solution to the problem by discrete coverage of a graph. The first method computes shortest paths and runs the Lloyd algorithm on the graph to obtain a centroidal Voronoi tessellation. The second method uses the Euclidean distance measure and locally exchanges mesh cells between approximated Voronoi regions to reach an optimal robot configuration. Both methods are compared and evaluated in simulations and in experiments with five robots on a curved surface.
