针对激光光斑图像或荧光小球等图像进行高斯拟合定位其中心坐标。可同时定位一幅图像中的多个小球。要求对象模型符合高斯分布。(For laser speckle images or small fluorescent balls image gaussian fitting location and its center coordinates. Can be positioning an image of the multiple balls at the same time. Request object model conforms to the gaussian distribution.)

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.
