说明：  在图像处理与模式识别领域，边缘图像的moments序列是进行图像分类的高效手段。 本程序提供了moments序列的计算代码，以及中心化正交化moments序列的代码，并提供有二三阶moment计算出旋转不变moments的代码。希望对各位有所帮助。
(In the field of image processing and pattern recognition, the edge of the image sequence of moments is a highly effective means of image classification. This procedure provides the calculation of moments code sequence, as well as the center of moments of orthogonal code sequences, and provide 23-order moment calculated spin moments of the code unchanged. I would like to help.)
