波原子变换代码，一种新的类方向小波变换，更好的表示图像(Wave atom transform code, the direction of a new class of wavelet transform, and better representation of the image)

非常好的人脸识 别的代码，有详细的注释，还有图片库，好东西就要大家分享！(Face recognition is very good code, there are detailed notes, as well as image libraries, will be a good thing to share!)

说明：  稀疏表示常用matlab代码，可以直接跑(Sparse representation commonly used matlab code, can run directly)

克里金插值法实现二维和三位等高线的绘制功能,()

对彩色图像特征提取，达到分类的目的，很好的(Image Feature Extraction)

说明：  一个EM算法实现图像分割，可以实现彩色图像分割。(An EM algorithm is used for image segmentation.)

说明：  数字图像处理 小波处理 ，去噪音，比基于傅里叶变换的去噪方法好。 含噪信号经过预处理，然后利用小波变换把信号分解到各尺度中，在每一尺度下把属于噪声的小波系数去掉，保留并增强属于信号的小波系数，最后再经过小波逆变换恢复检测信号。(The noisy signal is pre-processed, then the signal is decomposed into different scales by wavelet transform. The wavelet coefficients belonging to noise are removed at each scale, and the wavelet coefficients belonging to the signal are retained and enhanced. Finally, the detected signal is restored by inverse wavelet transform. It is better than the denoising method based on Fourier transform.)
