Choen-Sutherland算法裁剪线段 计算机图形学中使用Choen-Sutherland算法进行图形多边形裁剪，并用MFC实现(Choen-Sutherland )

4——连通填充算法的实现 1.用户能够用鼠标绘制多边形。 2.可以清除屏幕，重新绘制。 3.填充颜色及多边形的颜色(4- Connectivity filling Algorithm 1. Users to draw polygons with the mouse. 2. Can clear the screen, re-mapping. 3. Polygon fill color and the color)

1.图像尺度转换，降低图像分辨率，采用局部平均法、中值法；2.图像质量评价：均值、标准差、信息熵、平均梯度(1.Image scaling, reducing image resolution, using a local average、median method；2.Image quality assessment: the mean, standard deviation, entropy, average gradient )

说明：  一个用matlab编写的源程序，可以实现基于颜色直方图的图像检索(A source code written with matlab, you can achieve the color histogram-based Image Retrieval)

基于模板匹配的另一种人脸识别的算法，很实用，利用肤色建模来建立人脸皮肤模型(Another based on template matching algorithm for face recognition, very practical, using skin color modeling to create a human face skin model)

SIFT特征是图像的局部特征，其对旋转、尺度缩放、亮度变化保持不变性，对视角变化、仿射变换、噪声也保持一定程度的稳定性，亲身检测可用(SIFT feature is a local feature of image. It keeps invariant to rotation, scaling, brightness change, and also keeps a certain degree of stability to view angle change, affine transformation and noise.)

增强型Lee滤波，附有详细注释，简单易用，参数可调(enhanced LEE filter)

说明：  灰度图像的边界跟踪的方法，先用微分算子计算出图像的梯度图。然后再应用此算法。(Gray-scale image of the border tracking methods, first calculate the differential operator of the gradient map images. And then apply this algorithm.)

说明：  自由曲面光学透镜的图像变换面形测量系统与精度建模(Free-form optical lens image transformation shape measurement system with precision modeling)
