Abstract
Systems and methods for motion information transfer from visual to feature domain are disclosed which provide for mapping motion information from coding units in video content to corresponding convolution unit(s) in feature content. Systems and methods are also provided for improved decoder-side motion vector refinement of video content based on characteristics of corresponding feature units.
Claims7
A method of encoding video content with feature information, comprising:
- determine motion information for each coding unit comprising the video content;
- produce a feature map for the video content, the feature map having a plurality of convolution units with a correspondence to the convolution units;
- using a transformation selected based on the correspondence of the convolution units to the coding units, generate motion transformation information by mapping the motion information of the video content in each coding unit to at least one corresponding convolution unit;
- and
- generate an encoded bitstream including the video content, the motion information, and the motion transformation information.
