说明：  matlab图像去模糊算法代码，使用两倍长度的点扩散函数进行维纳滤波，模糊图像加入随机噪声，计算噪声信号功率比，使用噪声能量和图像一维自相关函数进行维纳滤波，模糊后的图像，减小噪声能量进行规则化滤波，增大拉格朗日乘子进行滤波，继续对恢复的图像反卷积，产生模糊图像，最初的PSF，显示最初PSF下恢复的PSF。(MATLAB image deblurring algorithm code, using double-length point spread function for Wiener filtering, adding random noise to blurred image, calculating noise signal power ratio, using noise energy and image one-dimensional autocorrelation function for Wiener filtering, blurred image, reducing noise energy for regular filtering, increasing Lagrange multiplier for filtering, continue to restore the image. Like deconvolution, a blurred image is generated. The original PSF displays the restored PSF under the original PSF.)

对图像实现分块操作 很实用的程序(Realize the image sub-block operation is very useful procedure)

对matlab中的GUI界面设计进行讲解并附有案例，例如如何进行界面菜单和控件设计，不同GUI之前函数传递，并讲解了如何调用自身函数(Matlab GUI interface design to explain the attached case, for example, how to interface menus and controls design, the different GUI function is passed before, and explain the how to call its own function)

说明：  阴影3D重建,对于人脸有效，基于yale2BDB(SFS, effective for face, based on yale 2 B database)

一个集成的图形界面的程序，可调用每一次作业子程序。 一、调用画点的函数，用DDA、中点算法画直线和中点算法画圆和椭圆。 二、多边形扫描转换算法和区域填充算法实现（扫描线算法为必做，基于求余运算的边缘填充和边标志算法为任选；基于种子的区域填充采用4连通区域的递归种子填充算法，或扫描线种子填充算法，要求种子点(x,y)可交互输入）。 三、线段裁剪和多边形裁剪算法的动画演示实现。（两种线段裁剪算法和H-S多边形逐边裁剪算法）多边形裁剪算法的动画演示要求先画出一个封闭的多边形，再画矩形的裁剪窗口，然后选择裁剪按钮（或命令），按下“上边裁剪”按钮（或执行“上边裁剪”命令），多边形相对裁剪窗口的上边进行裁剪，显示上边裁剪后的多边形，依此进行其它各边裁剪。 四、用动画实现二维图形变换的各种算法，实现对指定形体的平移、旋转和缩放。（包括类似自行车行走和绕固定点旋转的自旋转物体动画。） 五、简单三维图形系统：凸多面体的建模、透视投影，隐藏面的消除及基本图形变换（平移、旋转、缩放）。 六、交互式Bezier曲线的输入绘制程序实现 (An integrated graphical interface of the program, each operation subroutine callable. One call a function of the point of the painting, with the DDA, the midpoint algorithm for drawing a straight line and the midpoint algorithm circle and oval. Second, the polygon scan conversion algorithm and region filling algorithm (scan line algorithm for must fill and edge flag algorithm based on the edge of the modulo operator is optional using the 4 regional connectivity recursive seed filling algorithm based on the area of seed filling, or scan line seed filling algorithm requires the seed point (x, y) can be entered interactively). Line Clipping polygon clipping algorithm animation achieved. (Two Line Clipping Algorithm and HS polygon-by-side clipping algorithm) polygon clipping algorithm animation requires draw a closed polygon, rectangle and then draw the crop window, and then select the the cropped button (or command), press the "on top of cutting "button (or the implementation of)

用MATLAB实现的 基于dct的f3隐写(the f3 steganography based on the dct with matlab)

光谱微分（一阶、二阶微分）对高光谱遥感图像进行最佳波段选择 (Spectral radiant brightness)

泊松融合在某种意义上解决了图像融合的问题，但其在融合的过程中仅仅考虑了融入图像的梯度，而没有利用背景图像的梯度，因此，在使用泊松融合的过程中，需要对融入区域的标记较为准确，否则，会造成背景纹理的丢失，视觉上可以明显觉察图像融入的痕迹。因此，对公式稍作修改，在考虑前景的同时考虑背景的变化，可以得到更优的结果。(Poisson convergence in a sense solved the problem of image fusion, but it only considers the integration of image gradient in the integration process, but not the use of a background image gradient, therefore, the use of the Poisson integration process, the need for more accurate marker into the area, otherwise, it will result in the loss of background texture, image integration can clearly perceive the visual traces. Therefore, the formula slightly modified, in considering the prospect of taking into account the changes in the background, you can get better results.)
