说明：  该算法的功能是实现时频分析中多种分析方法后续处理中的图像压缩功能，进一步提高图像的时频分辨率(The function of the algorithm is to realize the image compression function in the subsequent processing of various analysis methods in time-frequency analysis, and further improve the time-frequency resolution of the image)

灰度图像的属性计算：利用bwlabel和regionprops函数对度量二值图像中目标对象的属性。(Attribute gray image: Using bwlabel and regionprops function measure binary image of the target object attributes.)

此程序为袁晓彤CVPR论文“基于多任务联合稀疏表示的的视觉分类”的主代码部分(The program for Yuan Xiaotong CVPR paper " visual classification with Muti-task joint sparse representation" main code of the parts)

小波方法的多焦点图像融合，用的融合规则为Yong Yang：A Novel DWT Based Multi-focus Image Fusion Method的方法(Wavelet method for multi-focus image fusion, the fusion rules: A Novel DWT Based Multi-focus Image Fusion Method method Yong Yang,)

该资料中的程序实现的是图像压缩，供初学者学习。(The data of the program implementation is the image compression, for beginners to learn.)

说明：  注：运行前自己准备图像，修改I = imread('')单引号中的路径 1. 给一张灰度图添分别添加高斯噪声和椒盐噪声。然后分别进行均值滤波和中值滤波，并把处理后的图片保存。 2. 图像频域处理，对图像进行傅里叶变换，进行高通滤波，显示处理结果。 3. 图像平移和旋转 4. 分别用OSTU阈值法和全局阈值法分割图像，然后进行腐蚀和膨胀处理，显示处理结果。(Note: Prepare the image by yourself before running, modify the path in single quotes of I = imread('')1. Add Gaussian noise and salt and pepper noise to a grayscale image. Then perform mean filtering and median filtering respectively, and save the processed pictures.2. Image frequency domain processing, Fourier transform of the image, high-pass filter, and display the processing result.3. Image translation and rotation4. Separate the image with OSTU threshold method and global threshold method, and then perform corrosion and dilation processing, and display the processing results.)

对双目视觉图像对进行匹配获取视差图，为后续三维重建做基础。(Binocular vision images are matched to obtain the disparity map, as a foundation for the subsequent three-dimensional reconstruction.)

关联下载,用于灰度相似度说明,欢迎下载使用,我感觉最好开源比较好(Download link for the gray-scale similarity shows that the use of welcome to download, I feel the best open source is better)

实现图像的分块压缩感知重建，DCT变换，OMP重构算法(Image block compressed sensing reconstruction, DCT transform OMP reconstruction algorithm)

说明：  可完成对MODIS09GA数据的批量格式转换与裁剪(Batch format conversion and clipping of modis09GA data)
