说明：  将基于小波变换的嵌入水印后的宿主图像进行压缩处理再提取灰度水印。(will be based on the wavelet transform the embedded watermark image of the host compressed again from Gray watermark.)

matlab实现的soble算法，自己输入阈值，然后得到边缘提取图像(matlab achieved soble algorithm, input their own threshold, and then get the image edge detection)

matlab图象应用广泛于图象增强,其中的Retinex图象增强也越来越受到重视,对于彩色图象的处理效果很明显。(Matlab image widely used in image enhancement, The Retinex Image Enhancement also growing in importance for color image effect is obvious.)

基于HIS空间的彩色烟雾图像分割算法，包含粗分，细分割与连通域提取(HIS color space based on image segmentation algorithm smoke contains coarse points, fine segmentation and connected domain extraction)

根据icip会议2005年度的一篇文章编写的matlab程序。包含有效果图。 运用smqt（连续均值量化变换）算法进行灰度图像增强。它比传统方法（直方图均衡化处理）的优点在于可以保证增强后图象的直方图波形不变，可以展现图象的底层结构，自动集中改进图象细节。是一种新的效果更好的灰度图象增强算法。(under icip 2005 annual meeting of an article prepared by the Matlab procedures. Includes map results. Smqt use (continuous quantitative mean transform) algorithm for gray-scale image enhancement. It is superior to the traditional method (histogram equalization processing) has the advantage can guarantee enhanced image histogram waveform unchanged. able to display images of the bottom structure, automatic focus on improving image details. Is a new and better results gray image enhancement algorithms.)

说明：  用于图像边缘检测，使用matlab检测图像边缘特征(For image edge detection, use matlab to detect image edge features)

1维LBP算法，在一维上做LBP算法，用于提取微表情特征(1-dimension LBP，abstract microfacial expression features)

利用傅立叶变换和相位相关法来检测图象的区域复制伪造(Use of Fourier transform and phase correlation method to detect forged images of the regional replication)

中值滤波：采用5*5窗口对噪声污染的图像进行去噪处理。(Median filter: 5* 5 window on the noise pollution to deal with the image de-noising.)
