Title:
IMAGE PROCESSING METHOD AND APPARATUS, COMPUTER DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/202285
Kind Code:
A1
Abstract:
Disclosed are an image processing method and apparatus, a computer device, and a storage medium, relating to the technical field of computers. The method comprises: obtaining an image processing model, wherein the image processing model comprises structure parameters, the structure parameters represent the structure of a metal artifact, and the structure parameters comprise first region structure parameters of a first region and second region structure parameters of a second region (201); when training the image processing model, adjusting the first region structure parameters on the basis of a training sample to obtain adjusted first region structure parameters; adjusting, on the basis of an angle difference between the first region and the second region, the adjusted first region structure parameters, and determining the obtained region structure parameters as adjusted second region structure parameters, a trained image processing model being used for removing the metal artifact in any medical image on the basis of the adjusted structure parameters (202).
