Abstract

Accurate and reliable automatic segmentation of faces in video footages is often hard to succeed, leading instead to laborious and tedious interactive manual segmentation. This paper presents a segmentation method that uses a few controlled sets of the weights on HSV components. First, it is shown that HSV has advantages over RGB or YCbCr when segmenting a face in image in such that a binary pattern reflects as many features of the face as possible. Then, a face detection system is constructed, in which each time a significant scene change is detected segmentation is carried out for the beginning frame of a new scene using a few sets of the weights on HSV components, and resulting patterns are correlated with a typical face pattern. Computer experiments show that the successful detection rate is more than 95 out of 100 faces.
