基于surf算法的复制移动检测，此方法适合图像伪造研究者初级实验(Replication mobile detection based on surf algorithm)

本程序实现了两种误差扩散算法，分别用Sierra扩散滤波器和stenenson扩散滤波器，实现了比Floy_stein更好的误差扩散半色调效果。(This procedure implements two error diffusion algorithm, respectively Sierra diffusion filters and stenenson diffusion filter, to achieve better than Floy_stein error diffusion halftone effects.)

生成相机标定所用的方格图，用于相机标定使用(Generates the grid chart used to calibrate the camera)

模糊聚类分割主函数及demo，直接运行就行，当然要有图片，呵呵(Main functions and fuzzy clustering segmentation demo, run directly on the line, of course, have pictures, Oh)

用于SIFT变化的关键点判断，定对比度和herrian矩阵，最后结果为关键点在DOG里的坐标！(Change for the SIFT key points to determine, set contrast and herrian matrix, the final results for the key points in the coordinates in the DOG!)

二维otsu的快速实验算法，具体可参考相应的文献。(Two-dimensional Otsu rapid test algorithm, specific reference to the corresponding literature.)

用于计算图像的频率响应，即SFR或者MTF(Can be used to calculate the image frequency response, namely SFR or MTF )

利用彩色图像的处理方法和数学形态学方法，编程计算荔枝果实的质心点的图像坐标(The use of color image processing method and mathematical morphology, image coordinates programmed to calculate the centroid of litchi fruit points)

传统滤波方式如均值滤波，中值滤波，维纳滤波对图像去噪的处理以及自适应中值滤波对图像去噪。(Traditional filtering methods such as mean filtering, median filtering, wiener filtering for image denoising processing and adaptive median filter for image denoising.)
