Document Type and Number:
WIPO Patent Application WO/2024/041108
Kind Code:
A1
Abstract:
The present application relates to an image correction model training method and apparatus, a computer device, a storage medium and a computer program product. The method comprises: acquiring a training image, and performing random data distortion on the basis of the training image to obtain a distorted image and distortion parameter information (202); inputting the distorted image into an initial image correction model for prediction to obtain initial correction parameter information, and on the basis of the initial correction parameter information, performing image correction on the distorted image to obtain an initial corrected image (204); on the basis of the initial correction parameter information and the distortion parameter information, performing loss calculation to obtain parameter loss information, and on the basis of the training image and the initial corrected image, performing loss calculation to obtain image loss information (206); and on the basis of the parameter loss information and the image loss information, performing iterative training to obtain a target image correction model, the target image correction model being used for prediction to obtain target correction parameter information, and performing image correction by using the target correction parameter information (208 and 210). Using the present method can improve the accuracy of image correction.
