Abstract

The invention discloses an image processing method and device, computer equipment and a computer readable storage medium. The method comprises the following steps: performing feature extraction processing on an under-sampling target image and a full-sampling auxiliary image to obtain an under-sampling target feature map and a full-sampling auxiliary feature map, and performing dimension reduction processing on the under-sampling target feature map to obtain an under-sampling target contrast channel feature; performing dimension reduction processing on the full-sampling auxiliary feature map to obtain full-sampling auxiliary contrast channel features, and performing contrast channel feature similarity processing according to the under-sampling target contrast channel features and the full-sampling auxiliary contrast channel features to obtain a similar contrast channel feature set; and performing feature fusion according to the similar contrast channel feature set and the under-sampling target contrast channel features to obtain a fused image. The fused image is reconstructed according to the similar contrast channel feature set and the under-sampling target contrast channel features, so that the quality of image reconstruction is ensured.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and device, computer equipment, and a computer-readable storage medium. Background technique [0002] When performing image processing, it is necessary to perform image fusion based on auxiliary images. For example, when processing a magnetic resonance imaging (Magnetic Resonance Imaging, MRI) image, the acquisition of the MRI image often takes the form of "paired acquisition". For example, MRI imaging of the knee is available in both proton density-weighted and fat-suppressed versions; these two images have visually similar anatomy and distinct contrast, and the former is time-consuming to scan tends to be lower than the latter. Therefore, it is a natural idea to utilize images acquired with assisted contrast to accelerate imaging of assisted target contrast, in combination with deep learning techniques. In related technologies, the...
