Edge detection result should be enhanced using linear method like Median filter to remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the centre of the pupil by counting the number of black pixels (zero value) of each column and row. Then get each row and column that has the maximum number of these black pixels. Then determine the center by simple calculation according to the image coordinate to set it correct on the image, consequently we can determine the radius of the pupil. Thus we can find the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms of circle and ellipse.

给定一个普通多项式p(x)，用列向量表示，阶次从高到低排列，此函数返回p(x)的切比雪夫多项式展开的系数，返回的的结果也是一个列向量，同样按切比雪夫多项式的阶次从高到低排列(Given a general polynomial p (x), with a column vector representation, the order highest to lowest, the function returns p (x) Chebyshev polynomial expansion coefficients of the returned result is a column vector, the same press cut the order highest to lowest Chebyshev polynomials)

A wavelet is a wave-like oscillation with an amplitude that starts out at zero, increases, and then decreases back to zero

LMD算法利用极值平均、边界局部特征尺度延拓、HDJ极值延拓法、基于ISBM延拓、平行延拓法等对数据拓展，降低端点效应。(The LMD algorithm uses the extreme value average, the boundary local characteristic scale extension, the HDJ extreme value extension method, based on the ISBM extension, the parallel extension method and so on to expand the data, reduces the end effect.)
