对称差分 meaning in Chinese

symmetric difference

Symmetrical frame difference was used to detect the motion area and a skin - color segmentation algorithm based on bp neural network was used to extract the face candidates . then , a combination of multiple neural networks , each corresponding to a certain range of face orientation , is used for face verification as well as for pose discrimination . experimental results show that the algorithm is robust for human faces under deep - view rotation , and is adaptive to various lighting conditions and different face sizes
提出了一种基于多种信息融合的多视角人脸检测方法.对视频图像通过对称差分算法检测运动区域,利用神经网络肤色模型对运动区域进行肤色识别,将多视角多人脸检测简化在候选区域内;最后通过集成多神经网络,其中每个神经网络负责一定视角的图像,实现了人脸验证,同时可以粗略地判定人脸姿态.实验结果表明该算法可适应不同的光照环境,检测不同大小,不同视角的人脸
