Abstract

The embodiment of the invention provides a model training method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining training sample data, the trainingsample data comprising at least one image pair, and the image pair comprising an original image and a transformation image of the original image; training the initial model based on the training sample data until the similarity between the hash code distribution probability of the original image and the hash code distribution probability of the transformed image meets a preset condition; whereinthe model takes an image as input, the hash code distribution probability of the image is taken as output, and the hash code distribution probability is the probability that the hash code corresponding to the image input into the model is each hash code in preset hash codes. According to the embodiment of the invention, the trained model meets the constraint condition, so that the Hash code distribution probability obtained through the model is similar, and the problem of poor robustness is solved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, the present disclosure relates to a model training method, device, electronic equipment and storage medium. Background technique [0002] In the prior art, for the original image, the user may make some changes to the image, such as rotating the image, adding a few words on the image, enlarging or reducing the image, and other simple transformation operations. Images are essentially the same or similar images, and theoretically the hash codes of images before and after transformation should be as identical as possible. [0003] However, in the way of obtaining the hash code of the image in the prior art, because the robustness of the hash algorithm is not strong, the robustness of the hash code of the image before and after transformation is often poor. Contents of the invention [0004] The purpose of the present disclosure is to at least solve one of the ...
