US Patent Issued to Huawei Technologies'Co., 'Ltd.' on Nov. 18 for "Error surface based sub-pixel accurate refinement method for decoder side motion vector refinement" (Indian Inventors)

ALEXANDRIA, Va., Nov. 18 -- United States Patent no. 12,477,142, issued on Nov. 18, was assigned to Huawei Technologies'Co.'Ltd.' (Shenzhen, China).

"Error surface based sub-pixel accurate refinement method for decoder side motion vector refinement" was invented by Sriram Sethuraman (Bangalore, India), Jeeva Raj A (Bangalore, India) and Sagar Kotecha (Bangalore, India).

According to the abstract* released by the U.S. Patent & Trademark Office: "Given that decoder side motion vector refinement/derivation is a normative aspect of a coding system, the encoder will also have to perform the same error surface technique in order to not have any drift between the encoder's reconstruction and the decoder's reconstruction. Hence, all aspects of al...
