摘要 介绍了基于图像的微运动测量的基本原理。对基于梯度的方法、块匹配方法、基于Fourier变换的方法、基于小波变换的方法以及基于信号统计特性的方法等几种常用的用于微运动测量的方法进行了分析和比较。通过分析发现,基于梯度的方法在微运动测量中具有很大的优越性。 The basic principle of micro-motion measurement based on images was introduced. Several micro-motion measurement algorithms were analyzed and compared, such as the gradient based methods, block matching methods, Fourier transform based methods, wavelet transform based method and statistical characteristic of signal based methods. The analysis result shows the gradient based methods have the superior performance in micro-motion measurement.
