Abstract
Methods, systems, and bitstream syntax are described for inter-frame coding using end-to-end neural networks used in image and video compression. Inter-frame coding methods include one or more of: joint luma-chroma motion compensation for YUV pictures, joint luma-chroma residual coding for YUV pictures, using attention layers, enabling temporal motion prediction networks for motion vector prediction, using a cross-domain network which combines motion vector and residue information for motion vectors decoding, using the cross-domain network for decoding residuals, using weighted motion-compensated inter prediction, and using temporal only, spatial only, or both temporal and spatial features in entropy decoding. Methods to improve training of neural networks for inter-frame coding are also described.
