But the personalized fitting experience is sacrificed for the fixed position and shape of the standard models, so it can’t meet the requirements of fitting and shopping guide in electronic commerce. To conquer the weakness a method is put forward which can custom-tailor shape characteristically using real personal images. A series of flat-panel models is established according to different types of build and degrees of fat. Afterwards a body model fitting the personalized customers is computed out by means of the interpolation method, and it can simultaneously show the texture changes coordinating to the chest and abdomen. On the basis of the body model, the original model body image and the clothes image fitting the model are transfigured. Anyone of customers can set the shape of body models exactly like themselves and have a vivid fitting experience.

摘要： 照片试衣有真实、快速、制作成本低的优势，但标准模特固定的姿势和体型却牺牲了个性化试衣体验，难以达到服装电子商务的试衣和导购要求。对此提出一种可以个性化定制体型的真人图片试衣方法：通过创建一系列不同身体类型、不同胖瘦程度的平板模型，使用模板插值的方法计算出符合用户个性化需求的身体模型，通过贴图变化实现胸部、腹部的大小变化，在此模型基础上对原始模特身体图像以及符合模特身材的服饰图像进行形变，最终使任何用户可以将模特设置成跟自己极其相近的体型来进行试衣体验。
