Abstract

The invention belongs to the fields of pattern recognition, computer vision and digital image processing, and specifically relates to a multi-attribute editing method, system and device for high-resolution face images, aiming to solve the problem that the prior art cannot realize high-resolution and controllable The problem of multi-attribute face image editing. The present invention includes: obtaining the feature expression of the input image through the encoder of the multi-attribute editing network; adjusting the tags to be edited in the original tag set to preset target tags; and expanding the adjusted tag set to image feature space resolution After the size is combined with the image feature expression; based on the combined feature expression, the attribute-edited image corresponding to the input image is obtained through the decoder of the multi-attribute editing network. The present invention uses wavelet transform to obtain high-frequency and low-frequency information of images, and combines the strategy of weighted and constrained attribute categories and reconstruction learning based on attribute mapping, so that high-resolution face images can be edited, and at the same time, controllable multi-attribute face image editing can be realized .

Description

Technical field [0001] The present invention belongs to the field of pattern recognition, computer vision and digital image processing, and specific to a multi-attribute editing method, system and device for high-resolution human face images. Background technique [0002] The ideal face attribute editing refers to a given property tab to change one or more attributes in a face image while maintaining the remaining properties and background. Common attribute editing has changed color, remove beard and age, and so on. [0003] Face Properties Editing gradually became a focus of research in computer visual directions due to its wide application in the fields of leisure entertainment, information security and face recognition. Face recognition technology has been deployed in a large scale of airport security, access control attendance, and public security criminal investigation, but there is still certain limitations for large human face age changes and large-scale face blindness. Fa...
