When stereo content (a; b) is manipulated (c), we quantify the perceived change considering luminance, and disparity (d), whereas previous work leads to wrong predictions (e) e. g., for low-texture areas, fog, or depth-of-field (arrows).Please note that all images in the paper, except for disparity and response maps are presented in anaglyph colors.

From left to right: Starting from an original depth map a pixel disparity map is computed and then a disparity pyramid is built. After multi-resolution disparity processing, the dynamic range of disparity is adjusted and the resulting enhanced disparity map is produced. The map is then used to create enhanced stereo image.

A temporal maximum speed volume (tMSV) takes the maximum blood-flow speed for each voxel throughout the cardiac cycle. An initial surface can be extracted from this static representation of the blood-flow regions. A standard marching cubes algorithm is employed to generate the iso-surface

Overview of the extraction approach: Based on the flow grid and the aneurysm ostium we seed streamlines at the ostium into the aneurysm. We identify several local line properties on the streamlines to compute a quality scalar field on the ostium. Given this scalar field we extract a seeding curve on the ostium, which is used to construct the boundary contour of the inflow jet. A second scalar field is computed on the aneurysm surface to indicate the impingement zone. Finally, we visualize both information expressively.
