matlab code for ultrasound image noise reduction

说明：  对数据的独立性进行分析，对数据的预处理（中心化和白化处理）(The independence of data analysis, data pre-processing (center-based and the whitening process))

自适应多尺度复合形态滤波，对信号或图像实现滤波(Adaptive Multi-scale Compound Morphology Filter)

通过数字图像相关的方法计算两幅图像之间的位移，计算时间较长，是最基础的DIC，没有优化。(Digital image correlation method to calculate the displacement between the two images, the time is longer, is the most basic DIC, no optimization.)

说明：  一个基于matlab的改进的灰度图像分水岭分割算法，该算法改进了普通的分水岭算法的过分割等问题，经过一系列处理可是分割结果更加准确。(Matlab based on gray-scale image of the improved watershed segmentation algorithm to improve the ordinary over-segmentation of watershed algorithm and so on, but after a series dealing with a more accurate segmentation results.)

生成静态散斑图，通过快速傅里叶变换，得到激光散斑图。(Generate static speckle pattern)

说明：  此算法可以实现任意两个图像的配准（整体平移） (This algorithm can achieve any two image registration (the overall translation))

计算峰值旁瓣比和积分旁瓣比的MATLAB程序(A MATLAB program for calculating the peak sidelobe ratio and the integral sidelobe ratio)
