Original Abstract Submitted
A problem with known SEI is that a relationship between a target image and an input tensor of a neural network model and a relationship between an output tensor and an output image are undefined or insufficient, and thus processing cannot be performed by simply using a model. Another problem is that in a case that the color component of the output image and the color component of the target image are different from each other, processing cannot be performed. An aspect of the present invention provides a video decoding apparatus including a prediction image derivation unit configured to decode a prediction image, and a residual decoder configured to decode a residual, wherein an input tensor is derived from a parameter indicating the number of channels of the input tensor and the output tensor of the neural network model or an image is derived from the output tensor.
