Original Abstract Submitted

This application discloses an encoding and decoding method and apparatus, and a computer device, and is applied to the field of image processing technologies. In the method, a feature map of an image is obtained through an encoding network. A boundary value of a first element in the feature map is determined, and a target range corresponding to the first element is determined based on the boundary value. If the first element is in the target range, entropy encoding is performed on the first element. If the first element is outside the target range, the first element is modified to the boundary value corresponding to the first element, and entropy encoding is performed on the modified first element, or the first element is marked as an out-of-bounds element, and variable-length code encoding is performed on the first element.
