KNN

说明：  用c语言写的三种常用的图像处理算法，包括边沿检测与提取，模板匹配和图象腐蚀膨胀细化(language used to write the three commonly used image processing algorithms, including edge detection and extraction. template matching and image thinning corrosion expansion)

小波包分解，求能量程序，，对小波包的了解掌握都很有用，希望对读者游泳(the wavelet packet decomposition and energy distribution )

包括常用的IHS,PCA 加权图像融合三种算法的Matlab源代码(Which are used in the IHS, PCA-weighted Image Fusion Algorithm three Matlab source code)

matlab计算二值图像几何特征中目标主轴长度(binary image matlab calculation of the geometric characteristics of the target length of major axis)

c源代码 图象的压缩编码，JPEG压缩编码标准 功能是行程编码，JPEG压缩编码（基本系统）(c code, function: jpeg stand for image show)

OFDM调制的的AWGN加瑞丽衰落信道,其它的我就不多说了(OFDM modulation of AWGN and ruili fading channel, the other I will not say)

这是个由matlab仿真实现的基于dwt的数字水印技术算法，实现了数字水印的嵌入、提取和一系列攻击实验。效果良好。(This is implemented by the matlab simulation of digital watermarking technique based on dwt algorithm, realization of the digital watermark embedding, extraction and a series of attacks on experiments. Good effect.)

dct和混沌相结合的图像加密，速度较慢但可以用来学习(DCT and chaotic combination of image encryption, slower but can be used to study)

说明：  图像重定向源代码，本文提出一种网格变形框架，允许显著特征进行均匀缩放，从而保证图像内容的完整性，将变形分布到不重要的区域。(The source code of optimal scale stretching image redirection is presented, and an effective image redirection algorithm is proposed to better guarantee the integrity of the image.)
