说明：  nsct图像处理代码，关于图像融合方面的(NSCT image processing code, about image fusion)

：介绍了一种基于小波变换的图像融合算法，它利用像素邻域平均梯度作为选择依据，对小 波变换后的高频系数进行选择，再逆变换完成图像融合．通过对红外热图与可见光图像的融合实验表明： 基于小波系数区域平均梯度的融合能使红外热图更加清晰，融合的图像光谱变异性较小，图像效果较好(: This paper presents a wavelet-based image fusion algorithm, which uses an average gradient of pixel neighborhood as selected on the basis of high frequency coefficients of wavelet transform to choose, and then inverse transform of image fusion. Through the infrared image and visible image fusion experiments show that: Based on the average gradient of wavelet coefficients of the regional integration of thermal infrared images can be more clarity, variability in integrated spectrum of images smaller, better image)

NJW算法，普聚类算法，利用3种拉普拉斯矩阵，作用在自制的数据集上(failed to translate)

这是清华大学章毓敏写的图像工程，分上中下三册，希望对学习图像处理的学者有所帮助。(This is the engineering of Tsinghua University Zhang Yumin, write the image points on the three, hoping to help scholars learn image processing.)

说明：  计算GIF彩色图像的差异，两幅图像大小一致且调色板一致。其中Psnr 为两幅图像的psnr值.P 为两幅图像之间像素索引不同的索引值占图像大小的比例。(GIF image color difference calculation, the two images the same size and same color palette. One Psnr the two images psnr value. P index for the pixels between two images, the index values of different ratio of total image size.)

自己编写的关于2013年的文章 a variational method for multi-source remote-sensing image fusion 的程序，基本实现了相关功能。(I have written a progrma about a variational method for multi-source remote-sensing image fusion publish in 2013,and the basic functions of the problems have been solved.)

ncc查询匹配的方法，可以用来做各种图像匹配的简单代码(ncc query matching method can be used for a variety of image matching short code.)

说明：  用于基本的envi熟悉认知，步骤清晰，亲历亲为，切实可用(It is used for basic envi, familiar with cognition, clear steps, personal experience and practical use)

对图像采用DCT变换后，进行图像去噪的算法(Image denoise by DCT)

说明：  ① 打开图片文件； ② 实现图像的放大、缩小功能； ③ 实现图像的黑白处理。 (black setting open file)
