matlab代码，可以直接运行，是一个M文件(matlabmatlabmatlabmatlabmatlab)

实现数字图像水印的嵌入与提取，文件分为两个，一个为嵌入，一个为提取(digital image watermarking)

This code is used to Solve the Center of picture.

利用wolfe-powell准则求解函数优化问题，使用不精确搜索法寻找最优步长，仿真正确。(Wolfe-powell guidelines for solving function optimization problems, the use of imprecise search method to find the optimal step length, the simulation is correct.)

Edge detection result should be enhanced using linear method like Median filter to remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the centre of the pupil by counting the number of black pixels (zero value) of each column and row. Then get each row and column that has the maximum number of these black pixels. Then determine the center by simple calculation according to the image coordinate to set it correct on the image, consequently we can determine the radius of the pupil. Thus we can find the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms of circle and ellipse.

说明：  压缩包内含有灰度变换，直方图均衡算法以及自适应直方图均衡算法，用于图像融合前处理环节，可用于图像增强，突出细节特征，可使用(The compression package contains gray-scale transformation, histogram equalization algorithm and adaptive histogram equalization algorithm, which can be used in the pre-processing of image fusion, image enhancement, highlighting the details, and can be used for image fusion.)
