一、观察序列频谱，观察信号通过系统后波形与频谱的变化。 系统函数，根据正准型结构（canonical form）编写样本处理算法。 (First, observe the sequence of the spectrum, observing the signal waveform and frequency spectrum through the system after the changes. System function, according to canonical structure (canonical form) the preparation of a sample processing algorithm.)

计算Local outlier factor的matlab实现，附带有例子。(Local outlier factor calculation matlab realize, comes with examples.)

Region growing algorithm for gray-scale images (1-channel). Implemented on MATLAB for segmentation.

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.
