离散傅里叶变换、离散余弦变化、离散小波变换(Discrete Fourier transform, discrete cosine transform and discrete wavelet transform)

说明：  一些关于图像阈值确定的matlab程序，包括迭代阈值，最小类内方差，最大熵，和用matlab库函数对图像进行边缘检测。可运行(Number of image thresholding matlab identified procedures, including iterative threshold, the smallest category of variance, maximum entropy, and the use of matlab library function of the image edge detection. Run)

This is the basic code implementing jpeg2000 in matlab

就用利用OPENCV亚像素级角点检测，这个方法对于初学代码程序的人来说很实用(On the use of the use of sub-pixel OPENCV corner detection, this method code program for the beginner who is very practical)

图像处理效果评价,评价指标包括峰值信噪比，熵，以及均方误差，具体公式请参考相关文献(photo)

Viola-Jones Fast Face Detection的matlab实现。(Viola-Jones Fast Face Detection Mex Implementation)

FLICM一种基于模糊局部信息C均值聚类方法，是对传统FCM聚类方法的最近改进方法，具有更强的鲁棒性，效果明显优于传统算法。(A novel and robust FCM framework for image clustering called Fuzzy Local Information C-means (FLICM) clustering algorithm.)

虹膜归一化的代码，只要给出定位好的虹膜图片，就可以很好的进行归一化，使用的极坐标变换。(Normalized iris code, as long as the position is given a good iris image, you can be a good uniform, the use of the polar coordinate transformation.)

稀疏矩阵字典的优化KSVD，本人已进行测试，效果甚佳,可以用在图像，数据的压缩和分类(Sparse dictionary optimization KSVD, I have been tested, very good results)

log Gabor小波图像纹理特征分析我小改過(log Gabor wavelet texture features of image I have little turn over)
