METHOD AND APPARATUS FOR RECONSTRUCTING IMAGE BASED ON NEURAL NETWORK

摘要

Disclosed is an image restoration method and apparatus using an extended neural network. An image restoration method according to an embodiment of the present invention includes receiving an input image; And restoring an output image for the input image using a neural network that satisfies a preset frame constraint condition, wherein the restoring step includes converting the input image into signals corresponding to different frequencies. ; Adjusting coefficients of the transformed signals using a nonlinear function; Restoring the adjusted coefficients; And inverse transforming the total coefficients determined using the reconstructed coefficients into the output image.
