图像中数字水印matlab编码，水印的嵌入提取及嵌入强度(Digital watermark image matlab coding, the embedded watermark extraction and embedding strength)

用matlab做的基于DCT变换的图像压缩源码，先把图像分成8X8 的子块，然后做DCT变换，再量化，在恢复重建图像(Using matlab to do DCT-based transform image compression source code, first image is divided into 8x8 sub-block, and then make DCT transform, and then quantified, at the resumption of the reconstructed image)

线阵ccd信号处理，信号放大预处理，采样保持，A/D转换，分析采集的到的图像信息，确定物体位置(signal prosessing of ccd)

目标跟踪中常用到的阿尔法-贝塔滤波 有图有真相(Target Tracking commonly used to Alpha- Beta filtering map with the truth)

说明：  meanshift算法实现目标的跟踪，由视频序列文件中提取出第一帧，定义目标区域，进行跟踪，动态显示跟踪结果(meanshift target tracking algorithm, by the video sequence documents to extract the first frame, the definition of the target area, tracking, tracking the results of dynamic display)

说明：  pcnn的matlab实现，pcnn神经网络主要用于图像去噪分割等(the realization of the matlab PCNN, pcnn neural network used mainly for segmentation, such as image denoising)

基于主动学习的高光谱遥感图像分类，主动学习方法也比较流行，新颖。(An Active Learning Approach toHyperspectral Data Classification)

实现函数imdilate的膨胀效果，自己编写的matlab函数实现。(Imdilate realize the expansion of function effect, I have written matlab function.)
