A method and apparatus for decoding data for still or video processing into a bitstream are provided. In particular, two or more sets of feature map elements are obtained from the bitstream. Each set of feature map elements relates to a feature map. Each of the two or more sets of feature map elements is then respectively inputted into two or more feature map processing layers out of a plurality of cascaded layers. The decoded data for picture or video processing is then obtained as a result of the processing by the plurality of cascaded layers. According to the present disclosure, the data may be decoded from the bitstream in an efficient manner in the layered structure.

Method and apparatus for decoding with signaling of feature map data

Methods and apparatuses are provided for estimating motion vectors of a dense motion field based on subsampled sparse motion field. The sparse motion field includes two or more motion vectors with their respective start positions. For each of the motion vectors, a transformation is derived which transforms the motion vector from its start point into a target point. The transformed motion vectors then contribute to the estimated motion vector on the target position. The contribution of each motion vector is weighted. Such motion estimation may be readily used for video encoding and decoding.
