计算“高位平面图像”的伪Zernike矩（低 6阶），并作为特征。(Computing " high dimensional images," the pseudo-Zernike moments (low order 6), and as a feature.)

也是利用最小二乘法对椭圆进行数据拟合，不过考虑到图像大小问题，这里只选取100个边缘点，点的个数也可以自行设置。(Ellipse is the least square method of data fitting, but taking into account the size of the image, here select only edge points 100, the number of points you can set your own.)
