模糊C均值算法

powell刚性图像配准，c++代码，通过查找非相关方向进行配准.(Polwell rigid image registration, c++ code, by looking for non-related directions for registration.)

说明：  比SSIM更新的图像质量评判算法VSNR(image quality assessment VSNR and its matlab code)

传统滤波方式如均值滤波，中值滤波，维纳滤波对图像去噪的处理以及自适应中值滤波对图像去噪。(Traditional filtering methods such as mean filtering, median filtering, wiener filtering for image denoising processing and adaptive median filter for image denoising.)

运用harr特征+SRC（稀疏表示）分类实现的一种车辆检测方法，文件中提供了训练和测试车辆图片。由于时间原因，所用haar特征没有优化，维度过高，导致滑窗框图过慢，本代码只输出效果统计数据，以供大家参考学习稀疏表示在车辆检测中的应用。(Using harr feature+SRC (sparse representation) classification to achieve a vehicle detection method, the paper provides a training and test vehicle picture. Due to time reasons, the use of haar feature is not optimized, high dimension, resulting in sliding sash figure is too slow, the effect of the code only output statistics for your reference learning sparse representation in the vehicle detection.)

该函数是用于计算峰值信噪比和信噪比的程序(it can be used to calculate psnr and snr)

说明：  经典的大津otsu算法在matlab中的实现程序，每一步都是经典步骤。(Otsu classical Otsus algorithm in matlab implementation process, each step is the classical steps.)

针对现有方法存在的隐藏容量低、操作不灵活的缺陷，文章提出了一种基于无损压缩的加密图像可逆 信息隐藏算法。(In view of the defects of low hiding capacity and inflexible operation of the existing methods, this paper proposes a reversible information hiding algorithm for encrypted images based on lossless compression.)

此算法是图像之间的转换，二值图，RGB等的相互转换源代码(This algorithm is the conversion between the images, the two value of the map, RGB, and so on the conversion of the source code)

程序是基于DSP的数字图像处理技术，可以实现军事滤波，中值滤波和维纳滤波，实现效果较好(The program is a DSP-based digital image processing technology, the military filtering, median filtering and Wiener filtering, better )

应用MATLAB小波工具箱中的一维小波包分析函数,采用默认阈值、调节后的阈值两种方法对含噪声的信号进行处理,并以一可见吸收光谱降噪为例,说明该方法在信号降噪中有效可行. (Application of MATLAB wavelet toolbox one dimensional wavelet packet analysis function, using the default threshold value, the adjusted threshold value of two kinds of methods including noise signal processing, and with a visible absorption spectrum noise reduction as an example to show the method is effective in signal noise reduction is feasible. )
