  • Methods and apparatus for optical blur modeling for improved video encoding
    Patent number: 10979704
    Abstract: Methods and apparatus of generating a refined reference frame for inter-frame encoding by applying blur parameters to allow encoding of image frames having blurred regions are presented herein. The methods and apparatus may identify a blurred region of an image frame by comparing the image frame with a reference frame, generate a refined reference frame by applying the blur parameter indicative of the blurred region to the reference frame, determine whether to use one of the reference frame and refined reference frame to encode the image frame, and encode the image frame using the refined reference frame when determined to use the refined reference frame.
    Type: Grant

    Date of Patent: April 13, 2021
    Assignees: Advanced Micro Devices, Inc., ATI Technologies ULC
    Inventors: Ihab M. A. Amer, Khaled Mammou, Vladyslav S. Zakharchenko, Dmytro U. Elperin
  • Content-adaptive B-picture pattern video encoding
    Patent number: 10097835
    Abstract: A method of video encoding is disclosed which is content adaptive. The encoding method is automatically adjusted to optimize the encoding, the adjusting depending on the content of the pictures being encoded. A system for implementing the method and a non-transitory computer-readable storage medium for storing instructions of the method are also disclosed.
