Abstract: An image processing method and apparatus, a device, and a non-transitory computer-readable storage medium are provided. In the method, a first feature map is obtained based on feature-encoding of an original image. A second feature map of the original image is obtained based on the first feature map. The second feature map includes noise information to be superimposed on the original image. A third feature map of the original image is obtained based on the first feature map. The third feature map includes different feature values. Each feature value represents a relative importance of an image feature at a position corresponding to the respective feature value. A noise image is generated based on the second feature map and the third feature map.
