Abstract

The invention provides an image recognition method, and relates to the field of artificial intelligence or information security. The method comprises the steps of obtaining a to-be-recognized image; inputting the to-be-recognized image into a pre-trained image recognition model to obtain a recognition result of the first portrait; wherein the image recognition model is obtained through training according to the following modes: obtaining a training image, and the training image comprises a second portrait area; determining a face area from the second portrait area; adding image noise into the face region to obtain a disturbance region; and training the image recognition model based on the disturbance area. According to the embodiment of the invention, the adverse effect of the background outside the face region on the model can be reduced during training, and the anti-attack defense capability of the trained model on the to-be-recognized image is further improved in a region enhancement mode. The invention further provides a training method and device, equipment, a storage medium and a program product.

Description

technical field [0001] The present disclosure relates to the field of artificial intelligence or the field of information security, and more particularly, to an image recognition method, training method, apparatus, device, medium and program product. Background technique [0002] The adversarial attack method can make the image recognition model output a feature vector with a large deviation by adding disturbance to the image to be recognized, and finally give a wrong recognition result. In order to improve the robustness of the image recognition model, adversarial samples can be used for training in advance to achieve the ability to defend against adversarial attacks. [0003] In the related art, adversarial samples are obtained by adding global perturbations to training images, and then image processing models are trained. However, image processing models trained with this class of adversarial samples cannot effectively defend against adversarial attacks. SUMMARY OF THE...
