文章讲诉的是小波在信号处理方面的应用，包括奇异点的检测，信号降噪等，有很全的原理介绍，有仿真程序和结论分析，具有一定的学习价值(V. article stresses that the wavelets in signal processing applications, including the singular point detection, signal noise, etc., have very wide introduction of the principle, procedure and conclusions have simulation analysis, has some learning value)

新发表论文Graph cuts based active contour model with selective local or global segmentation 附源码，基于图割的主动轮廓模型，用于有选择的局部分割或全局分割，欢迎下载！(Published Graph cuts based active the contour the model with selective local or global a segmentation attached source, the active contour model based on graph cuts for selected local partition or global segmentation are welcome to download!)

matlab代码实现meanshift图像分割算法，有较好的效果(matlab code meanshift realize image segmentation algorithm has better results)

说明：  基于contourlet的图像融合利用的融合策略是取像素绝对值最大。此方法用得较少，有学习价值(Contourlet based image fusion using the fusion strategy is to take the absolute value of the maximum pixel. This method is used less, the value of learning)

此程序计算图像的七个不变矩，提取出图像的形状特征，可用于图像检索。(This procedure of calculating the image of seven invariant moments, the shape of extracted image features, can be used for image retrieval.)

对低质量图像分割和计数，以大米照片为例。(Of low-quality image segmentation and counting to rice as an example photo.)

包括最后计算压缩图像的峰值信噪比和压缩效果的源码,用于信号特征提取、信号消噪，计算加权加速度。 ( Including the final calculation of the compressed image peak signal to noise ratio and compression of the source, For feature extraction, signal de-noising, Weighted acceleration. )

使用matlab实现的小波变换彩色图像水印嵌入和提取程序(Realize the use of matlab wavelet transform color image watermark embedding and extraction procedures)

分形图像压缩 效果好 但是运行时间长 需要改进(Fractal image compression effective running a long time but need to improve)
