Embodiments of the disclosure provide an encoding method, a decoding method, an encoder, a decoder, and a storage medium. The method includes the following. An encoding result of a current block, a target index for the current block, and a block-coding enable flag for the current block are obtained by parsing a bitstream. A feature map splicing order is obtained. When the block-coding enable flag is valid, target block-coding motion information corresponding to the target index is determined based on the feature map splicing order and pixel position information of the current block. The encoding result of the current block is decoded based on the target block-coding motion information.

Encoding method, decoding method, and decoder

An image processing method, an encoding method, an image processing apparatus, and an encoding apparatus are provided. The image processing method includes the following operations. An encoded bitstream is received from a trained encoder. The encoded bitstream is decoded by a trained decoder to obtain a decoded reconstructed image. The decoded reconstructed image or the decoded reconstructed image subjected to image post-processing is processed by a trained task execution network to perform or complete a machine learning task. The trained encoder and the trained decoder belong to a trained codec network.
