| Abstract: | 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. |
