Human Body Reshaping Based on Images

摘要

In this paper we present a method of human body reshaping which is based on 2D images. We first reshape a 3D human body from a 2D image by changing the 3D morphable circles in the 3D human body model, and then project the 3D model onto the original 2D plane. There are three main steps in our method. First, we can acquire the human body contour and the limbs information through the marks which were made by users. Secondly, we generate the 3D morphable circles from the body contour. The 3D morphable circle is a set of 3D annular points, and we can connect the points in each circle to create 3D meshes which can be used to generate the 3D human model. At last, we use texture mapping and affine transformation to reshape the body model and project it on to the 2D plan to implement the 2D images deformation algorithm. The method proposed in this paper can effectively combine 2D images with 3D graphics with little costs. The method is easy-to-use and has a definite application prospect in e-commerce and online entertainment fields. A lot of experiments illustrate that our method is acceptable.
