Human face and body fusion processing method and system

Abstract

The invention provides a human face and body fusion processing method. The method comprises the steps of obtaining a human head region; migrating a standard model body color to a human face skin color; setting a fusion background region; and performing Poisson fusion. The invention provides a human face and body fusion processing method and system. On one hand, the difference of human face skin colors of different people is relatively large and the fused target body color is fixed, so that for solving the problem of unnatural fusion of a human face image and a target body due to excessively large color (height) difference, the method for migrating the standard model body color to the human face skin color is adopted for ensuring that preprocessing before fusion can achieve the purpose of color natural transition. On the other hand, by limiting a boundary condition, transitional pixels of a human face jaw and the human head region are fused with a neck intersection region of a human body to remove the influence of the transitional pixels of the human face jaw.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a method and system for fusion processing of human face and body. Background technique [0002] With the development of human society, there are more and more choices of clothes. In the fast-paced life, people have the need to try on clothes without changing clothes, so virtual fitting products came into being. Virtual fitting technology can be roughly divided into two types: 2D and 3D. The models and clothing based on 3D virtual fitting technology are all made in 3D. The advantage is that the clothes and template body shapes can be seamlessly connected in 3D, and it has 360-degree visualization. The disadvantage is that 3D scanning of each piece of clothing is time-consuming and labor-intensive. Based on 2D virtual fitting technology, 2D image stitching is adopted, and the standard model is projected from 3D to 2D or directly in the form of 2D pictures. The advantage is that ...

Problems solved by technology

[0007] The present invention solves the problem of unnatural transition between the skin color of the human face and chin and the skin color of the neck and neck area of ​​the body of the standard model: due to the different skin colors of different people's faces and the different lighting environments for photographing, the skin color of different faces cannot be naturally transitioned from the skin color of the fixed body of the standard model; Since there are transition pixels from the head to the background in the extracted head image, if the transition pixels are directly pasted on the body of the standard model, it will appear abrupt, so it is necessary to process the transition pixels of the head image; if Poisson fusion is simply used, only If the chin area of ​​the face is fused with the body neck area of ​​the standard model, the color change of the chin will be very different from the color of other areas of the face, resulting in an unnatural effect
