Uncertainty Visualization In Forward And Inverse Cardiac Models

Posted on July 8, 2013April 16, 2024 by paul.a.rosen

Quantification and visualization of uncertainty in cardiac forward and inverse problems with complex geometries is subject to various challenges. In order to overcome these limitations in uncertainty visualization, we have developed and implemented a collection of novel approaches. Continue reading

A Flexible Framework For Fusing Image Collections Into Panoramas

Posted on July 8, 2013April 16, 2024 by paul.a.rosen

This paper introduces the Ray Graph - a general framework for panorama construction. With rays as its vertices, the Ray Graph uses its edges to specify a set of coherency relationships among all input rays. Consequently, by using a set of simple graph traversal rules, a diverse set of panorama structures can be enumerated, which can be used to efficiently and robustly generate panoramic images from image collections.

Visualization For Understanding Uncertainty In The Simulation Of Myocardial Ischemia

Posted on July 8, 2013April 16, 2024 by paul.a.rosen

We have created the Myocardial Uncertainty Viewer (muView) tool for exploring data stemming from the forward simulation of cardiac ischemia. The simulation uses a collection of conductivity values to understand how ischemic regions affect the undamaged anisotropic heart tissue. muView combines a suite of visual analysis methods to explore the area surrounding the ischemic zone and identify how perturbations of variables changes the propagation of their effects.

A Visual Approach To Investigating Shared And Global Memory Behavior Of Cuda Kernels

Posted on July 8, 2013April 16, 2024 by paul.a.rosen

We present an approach to investigate the memory behavior of a parallel kernel executing on thousands of threads simultaneously within the CUDA architecture. Our top-down approach allows for quickly identifying any significant differences between the execution of the many blocks and warps. As interesting warps are identified, we allow further investigation of memory behavior by visualizing the shared memory bank conflicts and global memory coalescence. Continue reading

Visualizing Robustness Of Critical Points For 2D Time-Varying Vector Fields

Posted on May 8, 2013April 16, 2024 by paul.a.rosen

In this paper, we introduce a new analysis and visualization framework which enables interactive exploration of robustness of critical points for both stationary and time-varying 2D vector fields. This framework allows the end-users to investigate how the stability of a critical point evolves over time. Continue reading
