This paper presents a face-tracking algorithm based on particle filter framework. Firstly, a target state is obtained using conventional color histograms. Secondly, a tracking method is proposed on the basis of seven moment invariants, and another state vector is also computed using this approach. Furthermore, the weights of the two state vectors are computed according to Euclidean distance between...
Human face detection plays an important role in many application areas such as video surveillance, human computer interface, face recognition, face search and face image database management etc. In human face detection applications, face region usually form an inconsequential part of images. Consequently, preliminary segmentation of images into regions that contain ldquonon-facerdquo objects and regions...
This paper proposed a robust and real-time face tracking method using particle filter based on skin color model and facial contour. Particle filter is an excellent tracking algorithm that can resolve no-linear and no-Gaussian problems. Skin color is used as an important cue since it is robust to various face poses and face rotations. A skin color model is constructed in YCbCr color space which is...
