Description: The radially averaged power spectrum (RAPS) is the direction-independent mean spectrum, i.e. the average of all possible directional power spectra. This function computes and plots the RAPS of an input image. The function was written to produce the RAPS for square weather radar reflectivity images so you will have to relabel the plot axes and title to suit your needs. The radially averaged power spectrum provides a convenient means to view and compare information contained in 2D spectra in 1D Platform: |

Description: HU不变矩程序代码很多，但是没找到一个完整准确的代码。本人对其中的某些代码修正后，和matlab计算结果进行比较，结果是一致的。本程序没有利用Opencv计算Hu矩的函数，好像opencv计算的M03和M30应该对调，否则，和matlab计算不一样！对旋转、缩放的图像进行测试，HU矩也是一样的，不信可以利用提供的图片对比一下。由于HU矩比较小，程序对HU矩取对数便于查看比较。总之，程序绝对安全可靠，可直接调用。-HU moment invariants code a lot, but could not find a complete and accurate code. I am, some of which code amendments, and matlab calculation results are compared, the result is the same. This procedure did not take advantage Opencv a function of the calculation Hu moments, like the M03 and M30 calculate opencv should be reversed, otherwise, and not the same as matlab calculations! Right rotation, scaling the image to test, HU is the same moment, and you do not believe you can compare the use of the images.
