1. A system for low compute depth map generation, comprising:
one or more processors; and
one or more hardware storage devices having stored computer-executable instructions that are operable, when executed by the one or more processors, to cause the system to:
obtain a stereo pair of images of a scene comprising two images of the scene;
generate a downsampled stereo pair of images by downsampling the stereo pair of images to reduce an image size of the two images of the stereo pair of images;
generate a depth map by performing stereo matching on the downsampled stereo pair of images; and
generate an upsampled depth map based on the depth map using an edge-preserving filter that utilizes (i) the depth map, (ii) at least some data of at least one image of the stereo pair of images, and (iii) at least some data from a prior depth map calculated for a prior timepoint, thereby reducing computational cost associated with generating a depth map based on an underlying stereo pair of images.
