利用mask与Wallis算法实现影像匀光匀色(Using mask and Wallis algorithm to realize the uniform color of the image)

求二维图像的极大值点与极小值点，很好用，希望对大家有帮助(image maximum points and minimum points, very useful)

摄影测量中影像匹配的程序，选择左右影像，可直接显示匹配结果。程序用C#编写(Photogrammetry image matching procedures, C# Prepared)

说明：  基于MODIS 大气水汽的计算，大气水汽含量(Atmospheric Water Vapor Calculation Based on MODIS)

说明：  如题，matlab手写数字测试图像处理 样本（30+50个）加全代码加测试结果(Like title, matlab handwritten digital test image processing samples (30 + 50) plus full code plus test results)

使用PCL库进行点云投影，朱德海《点云库PCL学习教程》第二章示例代码(Example code for Lidar cloud data projection)

atrous NSCT图像融合算法 可直接使用 带有实验测试图(atrous NSCT image fusion )

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.)

ENVI4.7及以上版本和IDL7.1以上版本,将高光谱遥感图像进行Savitzky-Golay光谱平滑滤波(ENVI4.7 above and IDL7.1 and above, hyperspectral images Savitzky-Golay smoothing filter spectrum)

提出了一种基于纠错编码的DCT域数字水印算法,该算法在检测时不需要原始图像,实现了盲检。并且对水印图像进行了利用超混沌置乱处理,提高了安全性能和抗攻击能力。纠错编码的引入使水印抗攻击能力明显增强。 (DCT digital watermarking algorithm based on error correction coding, the algorithm detected without the original image, blind. And watermark image of the the hyperchaotic scrambling process, improve the safety performance and anti-attack capability. The introduction of error correction coding watermark anti-attack capability significantly enhanced.)
