摘要
An apparatus for decoding an image, comprising: a memory storing one or more instructions; and a processor executing one or more instructions stored in the memory, wherein the processor is configured to: AI downscale an original image using a first DNN by the AI encoding apparatus Obtaining image data corresponding to a first image, reconstructing a second image corresponding to the first image based on the image data, and using a second DNN corresponding to the first DNN, the second image and the A third image obtained by AI upscaling the second image is obtained by performing an operation of the second parameters of the filter kernel included in the second DNN, and each of the second parameters is selected from the scale factor a2 and k integer values. It is expressed as one product, each of the k integer values is 0 or ±2 n (n is an integer), and the second parameters are determined as values associated with the first parameters of the filter kernel included in the first DNN.
