Title:
VIDEO ENCODING DEVICE AND VIDEO DECODING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/136257
Kind Code:
A1
Abstract:
A problem with conventional specific emitter identification (SEI) is that the relationship between a target image of a neural network model and an input tensor, and the relationship between an output tensor and an output image, are undefined or insufficient and cannot be processed using the model alone. Another problem of conventional SEI is that processing cannot be carried out if a color component of an output image and a color component of a target image differ. A video decoding device according to one aspect of the present invention comprises: a predicted image derivation unit that decodes a predicted image; and a residual decoding unit that decodes a residual, the video decoding device being characterized in that an input tensor is derived from a parameter designating the number of channels of an input tensor and an output tensor in a neural network model, or an image is derived from the output tensor.
