摘要
Disclosed are a system for coding an image or a video in a tool-by-tool manner based on a deep neural network (DNN), which is capable of applying DNN technology to implement all or a part of functions of an encoder and a decoder, and a method thereof. According to one embodiment of the present invention, the system comprises: a network training framework generating and transmitting a trained tool neural network described by training a DNN-based coding tool; an encoder, during an encoding process, applying the trained tool neural network to an inference engine in a first encoding process corresponding to the DNN-based coding tool, and applying a normalized image or video encoding tool in a second encoding process except the first encoding process to encode an inputted image or video so as to generate an encoded bitstream; and a decoder, during a decoding process, applying the trained tool neural network to an inference engine in a first decoding process corresponding to the DNN-based coding tool, and applying a normalized image or video decoding tool in a second decoding process except the first decoding process to decode the encoded bitstream generated by the encoder.
