Title:
IMAGE PROCESSING METHOD AND IMAGE PROCESSING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/272414
Kind Code:
A1
Abstract:
The present application provides an image processing method and an image processing apparatus, relating to the field of artificial intelligence. The method comprises: acquiring an input image; performing frequency division on the input image to obtain a plurality of frequency band components of the input image, the plurality of frequency band components being in one-to-one correspondence with a plurality of sub-networks in a super-resolution neural network; determining the number of operation layers of the sub-networks corresponding to each of the plurality of frequency band components; performing super-resolution processing on the input image by using the super-resolution neural network to obtain a plurality of super-resolution processing results corresponding to the plurality of frequency band components; and synthesizing the plurality of super-resolution processing results into an output image. According to the solution, the number of operation layers of each sub-network of the super-resolution neural network is determined mainly according to the plurality of frequency band components of the input image, and then the input image is processed by using the super-resolution neural network, thereby reducing occupied operation resources while ensuring the accuracy of the super-resolution processing results of the image, and improving the processing efficiency.
