【摘要】：随着科技的发展,特别是近几年互联网技术的迅速崛起,已出现了多款虚拟试衣软件,其中一类软件是基于三维场景,效果好,但成本高且可选服装受限;另一类软件是基于手机的,在试衣过程只是更换头部,达不到效果。本文结合数字图像处理中的相关技术设计了一款试衣软件。本文设计的试衣软件基本思想是将模特服装区域图像分割出来并匹配到衣者图像的服装区域中。因此本文的重点是介绍图像分割和图像匹配中的算法在服装试衣系统中的应用和实现。图像分割主要包括图像中人体区域分割和服装区域分割,本文主要综合边缘检测分割法、阈值分割法、区域生长分割法、灰度投影分割法,针对服装区域的特点,本文对区域生长分割法提出了一种改进算法,使服装区域分割更准确。图像匹配主要包括服装区域大小匹配、位置的匹配和肤色匹配。服装区域大小匹配重点是进行几何变换中的比例变换,根据试衣者的服装区域大小调整模特区域的大小;服装区域的位置匹配主要将服装中心轴与人脸中心轴对准,利用人脸识别方法确定人脸中心轴;肤色匹配是通过颜色模型变换将模特服装区中肤色与试衣者的肤色统一。该试衣系统具有自动化程度高、交互简单、适用范围广等特点,同时也具有一定的市场价值。
[Abstract]:With the development of science and technology, especially the rapid rise of Internet technology in recent years, there have been a number of virtual fitting software, one of which is based on three-dimensional scene, good effect, but high cost and limited choice of clothing; The other kind of software is based on mobile phone, in the fitting process only changes the head, does not achieve the effect. This paper designs a fitting software combined with the related technology of digital image processing. The basic idea of the fitting software designed in this paper is to segment the model clothing region image and match it to the clothing area of the clothing person image. Therefore, the emphasis of this paper is to introduce the application and implementation of image segmentation and image matching algorithms in garment fitting system. Image segmentation mainly includes human body region segmentation and clothing region segmentation. This paper mainly integrates edge detection segmentation, threshold segmentation, region growth segmentation, gray projection segmentation, aiming at the characteristics of clothing region. In this paper, an improved algorithm for region growing segmentation is proposed to make clothing region segmentation more accurate. Image matching mainly includes size matching, position matching and skin color matching. The emphasis of the size matching of clothing region is to change the proportion in the geometric transformation and adjust the size of the model area according to the size of the clothing area of the fitter; the position matching of the clothing area mainly aligns the clothing center axis with the face center axis. The face recognition method is used to determine the center axis of the face and the color matching is used to unify the skin color between the skin color and the color of the fitting person in the model clothing area by the transformation of the color model. The fitting system has the characteristics of high automation, simple interaction, wide range of application, and also has certain market value.
