Abstract

The invention relates to an image processing and image comparison model training method, device and system, a computer device and a readable storage medium. The method comprises the steps of obtaininga to-be-compared target image; inputting the target image into a pre-trained image comparison model, and outputting image features of the target image; wherein the image comparison model is obtainedthrough training based on a loss function including self-supervision loss, the self-supervision loss comprises loss between object classification data of different modal images of the same object in atraining sample, and the object classification data is obtained through classification processing based on image features; and comparing the image features of the target image with the image featuresof the base library images in the base library image group to obtain a comparison result. According to the method, the self-supervision loss is introduced for training, no extra marking cost is needed, and the cross-mode comparison accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image processing and image comparison model training method, device, system, computer equipment and readable storage medium. Background technique [0002] At present, there are more and more application scenarios based on face recognition technology. Under normal circumstances, the base library image used for face recognition is an RGB image, and because of the limitations of the dark light environment and other conditions, the captured image is an IR (Infrad, infrared) image, so there are face comparisons such as RGB images and IR images. Such cross-modal image comparison needs. [0003] A traditional solution is to train a convolutional neural network through the cross-entropy loss of multi-modal image training samples, and realize cross-modal image comparison based on the trained convolutional neural network. [0004] However, the above-mentioned cross-...
