Method and device for synthesizing human face images

Abstract

The invention discloses a method and device for synthesizing human face images, which support the synthesis of images including backgrounds, and no color mutations will be formed at the contours of facial features in the synthesized images. In the method of the present invention, the original face image and the face template image can be converted into the original face centered image after deformation and the face template centered image after deformation respectively, and a face mask image can also be generated, In the embodiment of the present invention, the original face centered image after deformation, the centered face template image after deformation, and the face mask image after deformation are fused. The background and human face in the original face image The background in the face template image can be adjusted in the face mask image according to the configured face grayscale parameters, so that it can support the synthesis of images containing the background. In the image, there will be no sudden change in color at the outline of the facial features, which improves the composite effect of the image.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for synthesizing human face images. Background technique [0002] The average face refers to extracting facial features from a certain number of ordinary faces, calculating the average value according to the measurement data, and then using computer technology to obtain a synthetic face. In the current average face calculation method, first extract a certain number of photos that need to get the average face group, then extract the facial features (except ears) contour of each photo, and then average it to get the average contour, for example, a big eye plus A small eye is a medium-sized eye, and then the average face is obtained by fusing the pixels of the image through the obtained average profile. [0003] The average face can be obtained in the average face calculation method in the prior art, and the average face has many applications. F...

AI Technical Summary

Problems solved by technology

In the image synthesis based on the average face, the replacement of the image part other than the face area is not supported, so that the edge contour of the synthesized face and the target face cannot be effectively integrated

In order to achieve replacement outside the face area, there is also a synthesis method that supports full-image replacement. This method will cause the background of the two images of the user's face and the target face to overlap when synthesizing the image, making the synthesized face impossible. The background of the target face is displayed, and the face contour in the synthesized image tends to form a color mutation at the contour of the facial features, and the image synthesis effect is poor
