This code detect face emotion from image. First, it takes an image, then detect the face using skin color segmentation.. Then it separates the eyes & lip from the face. Then it draws bezier curve for eyes & lips and compares them that are stored in t

包括图像打开，边缘检测，人脸识别，图片缩放，贝塞尔曲线等例子，全部调试通过，非常适合初学者学习。-Including open image, edge detection, face recognition, image scaling, Bezier curves, and other examples, all through debugging, very suitable for beginners to learn.
