中值滤波 原图像画面清晰，添加了椒盐噪声以后图像上出现了明显噪声，经不同模板的中值滤波处理后图像上的噪声被虑去，但使得图像变得模糊，并且，使用的模板越大，去噪声效果越好，同时图像也越模糊。滤波效果明显优于平滑滤波。 (Median filtering the original image, a clear picture of the Salt and pepper noise added after the image there is a clear noise, and by different template after median filtering has been taking into account the noise on the image to go, but makes the image become blurred, and, using the template more large, to noise, the better the effect, while the more blurred the image. Filtering effect is superior to smoothing.)

There are many compressed sensing (CS) recovery algorithms that have been proposed. Here I list some of them, and provide the corresponding experimental results. Essentially, the recovery algorithms are similar to the sparse coding based on the over-complete dictionary.

Heat equation with variable coeficients using Point Jacobi Method

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.
