Claim 0:
1. A method for detecting image information, wherein the method comprises:
acquiring at least one sample of image pair to be processed, wherein first image samples and second image samples of a same region acquired at two different time points are configured as samples of image pair to be processed;
inputting the samples of image pair to be processed into a first feature extraction model to be trained, extracting difference feature information between the first image samples and the second image samples;
inputting second image feature information corresponding to the second image samples and the difference feature information into a second feature extraction model, and reconstructing first reconstructed image feature information corresponding to the first image samples by the second feature extraction model;
calculating a reconstruction loss function of the second feature extraction model based on the first image samples and the first reconstructed image feature information;
inputting the difference feature information into a third feature extraction model and obtaining second reconstructed image feature information corresponding to the first image samples by the third feature extraction model;
calculating an adversarial loss function of the third feature extraction model based on the second reconstructed image feature information and the first image samples;
optimizing first model parameters in the first feature extraction model to be trained based on the reconstruction loss function and the adversarial loss function to generate an optimized first feature extraction model;
inputting the samples of image pair to be processed into the optimized first feature extraction model to generate difference information between the first image samples and the second image samples in the samples of image pair to be processed.
