求zernike矩 通过使用matlab的矩阵操作计算一幅图像阶为6重复度为6的zernike矩。(Find zernike matlab matrix operations through the use of an image calculated degree of order 6 Repeat zernike moments 6.)

说明：  kurtogram是一种四阶谱分析工具，用于检测和表征信号中的非平稳性。可用于轴承的故障诊断(The kurtogram is a fourth-order spectral analysis tool elaborated for detecting and characterising nonstationarities in a signal. It relies on the assertion that each type of transient is associated with an optimal (frequency/frequency resolution) dyad (f ; Df) which maximises the kurtosis. The Fast Kurtogram computes the kurtogram over a grid that finely samples the (f ; Df) plane. Its complexity is on the order of N log N. This is the "plain vanilla" code used in paper: J. Antoni, Fast Computation of the Kurtogram for the Detection of Transient Faults, Mechanical Systems and Signal Processing, Volume 21, Issue 1, January 2007, Pages 108-124.)

说明：  一个neural network的matlab源程序代码(a neural network to the source code Matlab)

大地测量中的坐标转换，高斯正算，matlab代码(Geodetic coordinate conversion, Gaussian positive operator, matlab code)

The p erceptro n algo rithm ceases to update the para meters only when all the training images ar e classified corr e ctly (no mistakes, no update s). So, if the training images are p ossible to clas sify co rrectly with a linear c la ss ifier, will the p erceptr on al gorithm find such a classifier? Yes , it does, and it w ill co nverge to such a classifier in a finite numb er of updates (mistakes ). We’ll sho w this in lectur e 2.
