MUMBAI, India, June 19 -- Intellectual Property India has published a patent application (202527097160 A) filed by Mediatek Inc. on October 08, 2025, for Method And Apparatus Of Bi-Directional Optical Flow Displacement Fusion For Video Coding.
Inventors include Lai, Chen-Yen; Chen, Guan-Hao; Lin, Wen-Chun; Chuang, Tzu-Der; Hsu, Chih-Wei; Chen, Ching-Yeh; and Chen, Yi-Wen.
The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: Method and apparatus of motion vector refinement using bi-directional prediction are disclosed. According to one method of the present invention, a first motion offset for a first predictor is determined based on a first reference picture and a second motion offset for a second predictor is determined based on a second reference picture separately by using a BDOF (Bi-Directional Optical Flow) motion model without a constraint for the first motion offset and the second motion offset to have a same magnitude, where the first motion offset is derived for a list 0 reference block and the second motion offset is derived for a list 1 reference block, where the first motion offset and the second motion offset are derived to minimize differences between the first predictor and the second predictor.
