Latest Patents
Qiang Chen's latest patents focus on video background subtraction using depth. The implementations described in these patents relate to methods, systems, and computer-readable media that enhance the rendering of foreground videos. The process involves receiving a plurality of video frames that include both depth data and color data. It further includes downsampling the frames, generating initial segmentation masks for each pixel, and determining a trimap that classifies pixels as known background, known foreground, or unknown. For pixels classified as unknown, weights are calculated and stored in a weight map. The method culminates in fine segmentation to obtain a binary mask for each frame, followed by upsampling the frames based on the binary mask to produce a foreground video.
