Abstract: In an abnormality recognition method, first-stage feature extraction is performed on a first image of an object to obtain a basic visual feature of the object. A first standard visual feature, which has a feature similarity to the basic visual feature that is greater than or equal to a preset threshold, is obtained by performing feature extraction on a second image belonging to a target object type. Second-stage feature extraction is performed on the first image based on target guidance information matching the target object type, to obtain a second visual feature. A comparison result is obtained by comparing the second visual feature with the first or a second standard visual feature of the second image. The second standard visual feature is obtained by performing the second-stage feature extraction on the second image. An abnormality recognition result of the first image is determined based on the comparison result.
