new edge-directed interpolation这篇文章所提算法的matlab实现(new edge-directed interpolation algorithm in this article referred to realize matlab)

将原始影像分别对RGB三色彩进行 x与 y轴之 Sobel边缘处理(original RGB images were of three colors for x and y axis of his Sobel Edge)

自动图像拼接，利用SIFT特征匹配算法，RANSAC(random sample consensus)算法，加权平滑算法等技术克服了传统图像拼接技术中的局限性(如光照、尺度变化的影响等)，实现了光照和尺度变化条件下的多视角无缝图像拼接(Automatic Image Stitching  Local features detection  Features Matching  Homography Estimation RANSAC Image blending )

是一个很好的图像拼接程序，先用sift算法提取两幅图片的特征点再用算法筛去错配点，把匹配点用线连接起来，注意：主函数是match.m，运行主函数后在命令框输入运行match( image1.jpg , image2.jpg )(Is a good image stitching program, the first two pictures with the sift algorithm feature extraction algorithm and then weed out the wrong point with point, the match point with a line linking Note: The main function is match.m, after running the main function Enter the run command box match (' image1.jpg' , ' image2.jpg' ))

采集一幅像素大于64*64黑白图像； 常规的数学统计数据处理：计算图象各象素点灰度值得均值、标准差、方差，并绘出灰度直方图； 采用[FFT（傅立叶变换）]对图像进行分析(Acquisition of a pixel is greater than 64* 64 black and white images The conventional mathematical statistical data processing: calculation of each pixel grayscale image is worth the mean, standard deviation, variance, and draw grayscale histogram The [FFT (Fourier transform)] to do image analysis )

C++语言实现的LSB数字水印算法，Visual C++亲测可用。(C++ language LSB digital watermarking algorithm, the Visual C++ pro-measurement available.)

遥感图像的色彩变换 能从IHS转换到RGB 并能从RGB转换到HIS 效果比较好(Remote sensing images from the IHS color transform to the RGB and the conversion from RGB to HIS conversion effect is better)

说明：  Demo for smoke effects on old NVIDIA GPUs.

基于非局部图像去噪模型的遥感图像融合的变分方法。该变分方法采用梯度下降法。(Variational method of remote sensing images nonlocal image denoising model fusion. The variational method using gradient descent.)
