利用数字图像处理里的方法得到的基于颜色和区域的人脸识别，包括单人和多人算法，单人算法效果比较好，对同色背景仍能很好的识别，多人算法效果一般，容易识别缺失(Face recognition based on color and region is achieved by using the method of digital image processing, including single person and multi person algorithm. The single player algorithm is better, and it can still identify the same color background. The algorithm of multi player is generally effective, and it is easy to identify missing.)
