Abstract:

An image processing method and apparatus in the field of artificial intelligence, being used for performing super resolution processing on an input image to efficiently and accurately obtain a higher-definition image. The method comprises: decomposing a first image to obtain a first structure sub-image and a first detail sub-image (601), wherein the first image is any one frame of image in video data excluding a first frame; fusing first hidden state information and the first structure sub-image to obtain a second structure sub-image, and splicing the first hidden state information and the first detail sub-image to obtain a second detail sub-image, wherein the first hidden state information comprises features extracted from a second image, and the second image comprises at least one frame of image of the video data adjacent to the first image; performing feature extraction on the basis of the second structure sub-image and the second detail sub-image so as to obtain a structure feature and a detail feature (603); and obtaining an output image according to the structure feature and the detail feature (604), wherein the resolution of the output image is higher than the resolution of the first image.
