houghcircle
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.

Prony
Prony算法用来提取信号的幅值、频率、衰减因子和初相角。它在电力系统低频检测,谐波检测等方面运用非常广泛,但是缺点是抗噪性差,它的信号提取能力强,模拟曲线的能力强,但为了提高它的抗噪性,最好与其它方法相结合(The Prony algorithm is used to extract the amplitude, frequency, attenuation factor and initial phase angle of the signal. It is in the power system low frequency detection, harmonic detection and other aspects of the use of a very wide range, but the disadvantage is poor anti-noise, and its signal extraction ability, simulation curve ability, but in order to improve its anti-noise, the best and other methods Combine)
