摘要
人们在玩游戏和网上试衣时,希望将自己的自拍图像替换到游戏角色和模特身上,从而获得较强的体验感。因此文章提出了一种复杂背景下人体头部图像替换算法,该算法首先采用人脸特征点检测算法检测出人头部的大致区域,然后在该区域内提取人脸轮廓并进行颈部的定位,最后进行颈部以上头部图像的获取及分辨率转换,替换到一个新的人体模特头像上。实验结果表明,该算法在复杂背景下能快速实现人的头部图像替换。
People hope to replace their self-image to the role of the game and the mannequin when people play games and online fitting.So an algorithm for the head Transplantation under the complex background is presented.The algorithm uses the facial feature point's detection algorithm to detect the approximate area of the head,then extracts face contour in the region and finally gets the head image above the neck and changes.The difficulty of this algorithm lies in extracting face contour and neck location.Experimental results show that the algorithm can quickly realize the human head image replacement in the complex background.
