Abstract: This disclosure describes techniques for performing semi-global matching (SGM) path cost compression. In some examples, the techniques may perform disparity-dependent sub-sampling of a set of SGM path costs where the sub-sampling ratio is determined based on a candidate disparity level. The sub-sampled SGM path costs may be stored in a memory. When retrieved from memory, the sub-sampled SGM path costs may be interpolated to reconstruct the other path costs not stored in the memory. The reconstructed path costs may be used for further SGM processing. In further examples, the techniques may perform disparity-dependent quantization on the SGM path costs or the sub-sampled SGM path costs, and store the quantized SGM path costs in memory. The techniques of this disclosure may reduce bandwidth as well as reduce the memory footprint needed to implement an SGM algorithm.

Abstract: Stitched images generated from combinations of multiple separate images mostly have irregular boundaries. Users generally prefer rectangular boundaries. Techniques for warping an image with irregular boundaries to give the image rectangular boundaries are disclosed herein. Preliminary warping of the image into the rectangle provides a rectangular shape on which to overlay a mesh. The image is reverted to its original shape with irregular boundaries and the mesh is warped accordingly. Global optimization is applied to the image by finding an energy minimum, or reduced energy below a threshold, for a function that gives the image a rectangular shape while preserving shapes and preserving straight lines. The mesh is warped according to the solution of the function and the image is stretched and/or compressed along with the mesh. This approach generates results that are qualitatively more visually attractive than other contemporary techniques.

Abstract: A temporal information integration dis-occlusion system and method for using historical data to reconstruct a virtual view containing an occluded area. Embodiments of the system and method use temporal information of the scene captured previously to obtain a total history. This total history is warped onto information captured by a camera at a current time in order to help reconstruct the dis-occluded areas.

Next, regions of current information are split using a classifier. The warped history information and the captured information then are merged to obtain an estimate for the current information and the reconstructed virtual view.
