The invention provides an image stylization processing method. The method comprises the following steps of inputting a content image into a first CNN model to obtain an initial image; determining a perceptual loss function according to the initial image, the content image and the style image, the style of the style image being used for performing stylization processing on the content of the content image; and training the first CNN model according to the perception loss function, and performing stylization processing on the content image by using the trained first CNN model to obtain a final stylized image. According to the scheme, the fusion degree of the characters and the background image is increased, meanwhile, the edge information of the character parts can be reserved, and the accuracy of recognizing the character parts in the image verification code by naked eyes can be improved while the safety coefficient of the image verification code is improved. In addition, the first CNNmodel is trained through the perception loss function, so that the reduction of the response time of the first CNN model is facilitated, and the training efficiency of the model is improved.
Description
technical field [0001] The present invention relates to the technical field of image processing, and more specifically, the present invention relates to an image stylization processing method, an image stylization processing device, a computer readable medium and electronic equipment. Background technique [0002] This section is intended to provide a background or context to the invention that is recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] With the general improvement of people's security awareness, image verification codes have been widely used in various Internet products to reduce products from malicious attacks, thereby ensuring people's Internet product experience.
