A Face Detection Method Used for Color Images

To the problem of face detection in color images, a novel method is proposed based on skin color segmentation and geometry features.Firstly, some common color models are analyzed, and a large amount of skin images are used to establish an YCbCr color model for region segmentation.Then, the morphological processing is executed on the binary image, and the facial regions filtering is conducted by adopting some geometry constraints such as Euler number, the ratio of width and height, centroid.Finally, the face region is located and labeled with a rectangle.Experimental results showed that the proposed method can equilibrate the unbalance between good accuracy and real-time performance to some extent, and is effective in face location.
