Method for automatically beautifying skin of facial image

Abstract

The invention provides a method for automatically beautifying skin of a facial image. The method comprises the following steps of (1) feature extraction: carrying out face detection and face feature extraction on an original facial image; (2) layer decomposition: carrying out image component composing on the original facial image to obtain a brightness layer, a smoothness layer and a color layer; (3) mask generation: utilizing the face features to respectively generate a corresponding brightness mask, a smoothness mask and a color mask for the brightness layer, the smoothness layer and the color layer; (4) beautification parameter optimization: computing beautification parameters corresponding to the three layers with an average face as a standard template; (5) layer enhancement: utilizing the beautification parameters and the masks to carry out beautification processing on the three layers respectively so as to obtain a beautified brightness layer, a beautified smoothness layer and a beautified color layer; and (6) layer fusion: fusing the three beautified layers to obtain a final face beautification image.

Description

technical field [0001] The invention belongs to the field of face image recognition and processing, in particular to an automatic method for beautifying the skin of a face image.

AI Technical Summary

Problems solved by technology

Existing facial skin beautification systems generally only deal with certain skin attributes, and there is still a lot of room for improvement in beautification effects

[0005] In addition, in the original face image, the image components corresponding to the three skin attributes are fused together. The current skin beautification methods generally do not decompose the corresponding image components, resulting in the mutual influence of different skin attribute operations during the beautification process. , resulting in some deviation in the final beautification effect
