说明：  将基于小波变换的水印嵌入后的宿主图像加噪处理再提取灰度水印。(will be based on the wavelet transform the watermark embedded in the host Image Noise from Gray again watermark.)

方向梯度直方图的全部代码，广泛应用于行人检测行人检测(Histogram of Oriented Gradients code Pedestrian Detection)

利用霍夫曼编码对图像进行编码及解码，计算霍夫曼编码效率(huffman encode and decode)

说明：  MATLAB实现数字图像处理和函数绘图的学习，不仅可以掌握基本MATLAB的使用，而且是数字图像处理的入门级学习。(The learning of digital image processing and functional drawing by MATLAB can not only grasp the use of basic MATLAB, but also be an entry-level learning of digital image processing.)

说明：  改进拉普拉斯能量和的尖锐频率局部化 Contourlet 域多聚焦图像融合方法(Sum-modified-Laplacian-based Multifocus Image Fusion Method in Cycle Spinning Sharp Frequency Localized Contourlet Transform Domain)

说明：  实现目标检测的代码，有例程视频，可以运行(Achieve target detection code, there are routine video, you can run)

ostu与鱼群算法相结合，并且用matlab实现(ostu algorithm combined with the fish, and using matlab)

说明：  小波模极大值用于边缘特征提取.很好的一个matlab算法，可以直接验证。(Wavelet modulus maxima for edge feature extraction algorithm matlab good one can be directly verified.)

多幅图像的加密技术 matlab源代码(image encryption technology Matlab source code)

该程序初始时使用背景差分法自动检测目标，当目标完全进入图像中后，改用meanshift方法对目标进行跟踪。(the program use background subtraction to detect the target first,when the target fully enter the screen,change to meanshift method to track the target.)
