Face image composition method and device

Abstract

The invention discloses a face image composition method and a device which support image composition containing background, and color change can not occur in facial features outline in the composited image. In the method of the method, an original face image and a face template image can be converted as a shape-changed original face centered image and a shaped-changed face template centered image, and a face masking image can be also generated, in the embodiment of the invention, the shape-changed original face centered image, the shaped-changed face template centered image and the shape-changed face masking image are composited, the background of the original face image and the background of the face template image can be adjusted in the face masking image according to the configured face gray parameters, so that the image composition containing background can be supported, skin color balancing is performed on the original face centered image, so that color change can not occur in the facial features outline in the composited image, and the composition effect of the image can be improved.

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
