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.

APF仿真的matlab工程文件，对于学习APF原理有帮助(APF simulation matlab project files, helpful for learning the principles of APF)

功能较全面的计算器，除了简单的四则运算之外，还增加了三角函数、幂函数和对数函数，另外还增加了shift功能键，可以用来计算反三角函数。使用方法：使用前将.m和.fig文件放到matlab工作目录下（本人R2013放到bin文件夹下）(More comprehensive calculator function, in addition to simple arithmetic, but also increased the trigonometric, exponential function and logarithmic functions, in addition to increasing the shift function keys can be used to calculate the inverse trigonometric functions. Usage: Before using the m and fig files into the matlab working directory (I R2013 into bin folder))
