摘要
头肩序列图像的人脸跟踪有着广泛的应用 ,但目前的大多数跟踪算法难以同时满足精确与快速的要求 .本文提出了一种基于器官跟踪的人脸实时跟踪算法 ,利用形态学运算对嘴进行跟踪 ,进而通过对人脸对称性的分析 ,实现了对头肩序列中人脸的跟踪 .由于算法只涉及简单的形态学运算[1] 和局部的旋转运算 ,速度达到实时要求 ,同时人脸对称性的分析保证了跟踪结果的精确性 .
There are a great varitety of applications of tracking human faces in head shoulder sequences.However,most tracking algorithms,so far,are unable to meet the demands for both precise and fast tracking.A real time algorithm,based on organ tracking,for tracking human faces in head shoulder sequences is presented in this paper.The algorithm implements tracking the human face by tracking the mouth with morphology,then analyzing the symmetry of the face.The simplicity of morphological and the local rotating operations enable real time tracking.Meanwhile,the analysis of the symmetry of the face guarantees precise tracking.
