Face detection is one of the challenging problems in Computer Applications. The main part is to detect the face portion from the entire image. In this paper, the authors used YCbCr to detect the skin color of humans by setting appropriate thresholds. The reason for using this color model is to remove the illumination component, Y. They have proposed and implemented a method to locate the face portion of human by determining the number of holes in the skin region using Euler's method and also by taking eye distance.
