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.

水声信道TEQ
本文在确定了水声信道的数学描述后,提出了在信道自适应过程中,可以应用
子波对信号进行多分辨率分解,逐尺度地对信道进行均衡. 这样,不但减少了运算数
据量,也减少了均衡所需的权系数个数.(equalizer)
