传统聚焦评价函数

人脸检测,是采用国外的一个论文中的算法实现，如果想要论文，请发信给我(face detecting)

图像处理中经常需要检测圆形状的物体，该程序用霍夫变换可以检测圆的圆心和半径。(Image processing often requires detection of a round-shaped objects, the program can detect the use of Hough transform and radius of the center circle.)

说明：  图像采集，简单的c#联合halcon做ncc模板匹配的操作(Image acquisition, simple C# combined with Halcon to do NCC template matching operation)

python语言，使用卷积神经网络的特征做图像检索(image retrieval using CNN)

陆文凯老师数字图像处理第二次作业，前景背景分割和前景区域面积计算(Wen-Kai Lu a teacher of digital image processing a second operation, the background segmentation and the prospects for the future size of the area calculation)

这是本人自己实现的椭圆检测算法，基于MATLAB实现，经测试对一些图片椭圆检测效果较好，需要同学可以参考(This is my own implementation of ellipse detection algorithm based on MATLAB implementation, tested on a number of pictures ellipse detection is better, students can refer to the need to)

三维最大Renyi熵的灰度图像阈值分割算法(Maximum Renyi entropy of three-dimensional gray-scale image segmentation algorithm)

数字图像处理，图像质量评价指标，matlab 计算图像峰值信噪比(Calculation of peak signal to noise ratio)

说明：  利用梯度算子对图像边缘进行计算，比较得出清晰度评价值，进行取得最佳清晰度图片(The gradient operator is used to calculate the edge of the image, and the sharpness evaluation value is obtained by comparison to obtain the best sharpness image)

说明：  Arnold 变换与 Gray 码变换相融合的双置乱算法程序，包括了加密和解密程序(The program of double scrambling algorithm combining Arnold transform and gray code transform, including encryption and decryption program)
