本代码是基于k-mean聚类的关键帧提取代码，是用matlab来实现的。(The code is based on k-mean clustering key frame extraction code, using matlab to achieve.)

matlab数据分析的经典算法，可以用于数据分析(matlab data analysis of the classic algorithms, can be used for data analysis)

牛顿迭代法求无约束一维极值问题的速度相当快，而且还有一个好处就是能高度逼近最优值。(Newton iteration method for one-dimensional unconstrained extremum problem very fast, but there is a benefit that can be highly close to the optimal value.)

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.

成像处理一般包括三个步骤：1、距离向脉冲压缩，对一个合成孔径内的每个回波脉冲均进行压缩；2、距离徙动矫正，把属于同一点目标的脉冲校正到等距离线上、3、方位向脉冲压缩。(Imaging process generally comprises three steps: a distance to the pulse compression of echo pulses each have an inner aperture compression 2, range migration correction, the pulses belonging to the same point in the correction target line equidistant , 3, azimuth compression to pulse.)
