Title:
IMAGE-GUIDED DEPTH PROPAGATION FOR SPACE-WARPING IMAGES
Document Type and Number:
WIPO Patent Application WO/2022/191628
Kind Code:
A1
Abstract:
Updating an image during real-time rendering of images by a display device can include determining a depth for each pixel of a color frame received from a source device and corresponding to the image. Each pixel's depth is determined by image-guided propagation of depths of sparse points extracted from a depth map generated at the source device. With respect to pixels corresponding to an extracted sparse depth point, image-guided depth propagation can include retaining the depth of the corresponding sparse depth point unchanged from the source depth map. With respect to each pixel corresponding to a non-sparse depth point, image-guided depth propagation can include propagating to the corresponding non-sparse depth point a depth of a sparse depth point lying within a neighborhood of the non-sparse depth point. Pixel coordinates of the color frame can be transformed for generating a space-warped rendering of the image.
