A method and system for fusion processing of human face and body

Abstract

The invention provides a method for fusion processing of human face and body, which includes the process of obtaining the human head area; transferring the body color of the standard model to the skin color of the human face; setting the fusion background area; and performing Poisson fusion. The present invention proposes a face and body fusion processing method and system. On the one hand, due to the large differences in the skin color of different people's faces, the target body color for fusion is fixed. When the difference in brightness) is too large, the fusion is unnatural. The method of transferring the skin color of the standard model to the skin color of the face is adopted to ensure that the preprocessing before fusion can achieve the purpose of natural color transition. On the other hand, by limiting the boundary conditions, the transition pixels of the face chin and the head area are fused with the intersecting area of ​​the human neck and neck to remove the influence of the transition pixels of the face chin.

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
