说明：  預失真是一種用於改善無線電發射機放大器線性度的技術。大多數電信系統中的無線電發射機放大器需要是“線性的”，因為它們必須準確地再現其輸入端存在的信號。 壓縮其輸入或具有非線性輸入/輸出關係的放大器導致輸出信號濺到相鄰的射頻上。 這會對其他無線電信道造成乾擾。(Predistortion is a technique used to improve the linearity of radio transmitter amplifiers. Radio transmitter amplifiers in most telecommunications systems are required to be "linear", in that they must accurately reproduce the signal present at their input. An amplifier that compresses its input or has a non-linear input/output relationship causes the output signal to splatter onto adjacent radio frequencies. This causes interference on other radio channels.)

经典匹配追踪程序。附带经典lena图像、并对其进行处理。(Classic match-tracing program. With classic lena image and its processing.)

说明：  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.
