[0030] The present invention will be further described below in conjunction with the accompanying drawings.
[0031] The system structure diagram of the present invention is as attached figure 1 As shown, the specific steps are as follows:
[0032] (1) Use a cascade classifier based on Haar-like features (such as the Viola-Jones face detector in the open source computer vision library OpenCV) to perform face detection on the original face image;
[0033] (2) According to the detected face, extract the shape feature (Fs) of the face image;
[0034] (3) Extract the brightness features and edge features of the face image (F);
[0035] (4) According to the requirements of specific image editing, using the shape features, edge features and brightness features of the extracted face image, the region-aware mask generation (M) is realized by solving a weighted least squares formula.
[0036] The specific steps of the present invention extracting the face image shape feature (Fs) ar...
