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.

This function takes the n time domain samples (real or complex) and finds the psd by taking (fft/n)^2. The two sided spectrum is produced by shifting the psd The array freq provides the appropriate frequency values for plotting purposes. By taking 10*log10(psd/max(psd)) the psd is normalized values beow 60db are set equal to -60db

基于傅立叶－梅林变换的matlab图像配准程序，可以灵活设置待配准图像的大小及旋转角度等，配准前可以选择多个参数控制配准结果，可以显示配准后的图像及图像间的具体变换参数以及中间结果等(Based on Fourier- Mellin transform matlab image registration procedures, registration can be flexibly set the image size and rotation angle, registration before you can select multiple parameter control registration results, you can display the images and post-registration between images specific transformation parameters and intermediate results)

可以实现FFT变化的时域图分析，可以清楚的知晓信号随时间的规律变化(Changes can achieve FFT time domain analysis, the signal can be clearly aware of the law change with time)
