Real-time rendering applications exhibit a considerable amount of spatio-temporal coherence. This is true for camera motion, as in the Parthenon sequence (left), as well as animated scenes such as the Heroine (middle) and Ninja (right) sequences. Diagrams to the right of each rendering show disoccluded points in red, in contrast to points that were visible in the previous frame, which are shown in green (i.e. green points are available for reuse).

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.

Standard 4,0962 shadow map with perspective warping, rendering at 64 FPS (left). QVSM with a maximum refinement level of 32 × 32 and 1,0242 tiles, rendering at 32 FPS (right). Adaptive subdivision effectively removes aliasing in cases that are difficult for reparametrization and global partitioning methods.
