Title:
IMAGE PROCESSING METHOD AND APPARATUS FOR ARTIFACT REMOVAL, AND DEVICE, PRODUCT AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/202265
Kind Code:
A1
Abstract:
Provided in the embodiments of the present disclosure are an image processing method and apparatus for artifact removal, and a computer program product and a storage medium. The image processing method in the present disclosure comprises: establishing a training data set used for training a neural network; performing artifact removal processing on an artifact-containing image by using an adaptive convolutional dictionary network, so as to obtain a processed image; and on the basis of an artifact-free image, the processed image, and an objective function which has been subjected to image mask processing, performing iterative training on the adaptive convolutional dictionary network, so as to optimize network parameters of the adaptive convolutional dictionary network. By means of the image processing method in the present disclosure, artifacts in an image can be simply and effectively removed to obtain a clearer image which is not interfered with by the artifacts.
