  • 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.
