说明：  利用MATLAB的图像用户界面GUI设计一个简单的菜单式图像处理系统。通过该程序实现对图像的简单处理、变换和去噪等功能，满足课程设计的要求。(A simple menu image processing system is designed by using the image user interface GUI of MATLAB. Through this program, the functions of image processing, transformation and denoising are realized, which meet the requirements of curriculum design.)

说明：  区域生长算法，用于图像分割。 运行RunGrow.m 修改文件名即可。(Region growing algorithm for image segmentation. Run RunGrow.m modify the file name.)

matlab中实现grabcut，已经编译调试好了，直接运行就可以了(the code of grabcut,you can run it in matlab without debug)

新的形态学图像增强，采用多尺度形态学增强算法，对图像进行增强(morphology image enhance )

说明：  SIFT特征点的提取和匹配，SIFT算法首先在尺度空间上进行关键点检测，确定关键点的位置和关键点所处的尺度，然后使用关键点邻域梯度的主方向作为该点的方向特征，最后由关键点邻域梯度信息生成关键点的特征向量(SIFT algorithm firstly detects the key points in the scale space, determines the location of the key points and the scale of the key points, then uses the main direction of the key point neighborhood gradient as the direction feature of the point, and finally generates the feature vector of the key points from the key point neighborhood gradient information)

自己编写的数学形态学膨胀和腐蚀的matlab算法 适用于二值和灰度图象 (I have written mathematical morphology and corrosion expansion matlab algorithm for binary and gray-scale image)

小波滤波器设计和去噪matlab经典程序，给出了简单的滤波器设计，并用其进行了去噪处理(Wavelet filter designing and denosing)

说明：  很好用的三维重建软件，VisualSFM软件允许上传一系列图像，它从这些图像中找到每一个图像的特定特征，利用这些特征信息重建出3D模型的稀疏点云，而后还可进行稠密点云重建。(The VisualSFM software, a good 3D reconstruction software, allows uploading a series of images. It finds the specific features of each image from these images, and USES these feature information to reconstruct the sparse point cloud of the 3D model, and then it can reconstruct the dense point cloud.)
