FACE DETECTION IN COLOR IMAGES BASED ON MULTI-RESOLUTION SUB-IMAGE FUSION

摘要

A face detection method in color Images, using multi-resolution sub-images Fusion and face modes, is proposed. Firstly the skin image is obtained by two different color modes (HSI and YCbCr). Secondly, Multi-Resolution Sub-image is gained by wavelet analysis of skin area image. Thirdly Fusion image can be obtained by sub-image LH and HL according to pixel fusion criterion. Candidate face area can be detected in fusion image. Finally face images can be validated through template matching method. Experiment result shows that, detection rate of faces in a complex background is high, but several faces in a group photo would be detected as one face if they are too close.
