Patent number: 11973985Abstract: Various schemes pertaining to pre-encoding processing of a video stream with motion compensated temporal filtering (MCTF) are described. An apparatus determines a filtering interval for a received raw video stream having pictures in a temporal sequence. The apparatus selects from the pictures a plurality of target pictures based on the filtering interval, as well as a group of reference pictures for each target picture to perform pixel-based MCTF, which generates a corresponding filtered picture for each target picture. The apparatus subsequently transmits the filtered pictures as well as non-target pictures to an encoder for encoding the video stream. Subpictures of natural images and screen content images are separately processed by the apparatus.Type: GrantFiled: August 22, 2022Date of Patent: April 30, 2024Assignee: MediaTek Inc.Inventors: Chih-Yao Chiu, Chun-Chia Chen, Chih-Wei Hsu, Tzu-Der Chuang, Ching-Yeh Chen, Yu-Wen Huang
