The human face is a complex pattern. Finding human faces automatically in a scene is a difficult yet significant, problem. This is the first important step in a fully automatic human face recognition system. The authors have proposed a hierarchical knowledge-based face detection system to locate human faces in a complex background. In this system the higher levels are based on the mosaic images. In this paper the authors introduce several characteristics of the mosaic images and their application in the human face location. A mosaic image with certain size of cells may present the region features of a face. In this research the authors solved the problem of finding human faces in a picture with complex background when the size and number of faces are unknown.
