用matlab实现的白平衡算法，检测图像中的高亮点作为理想白点，计算校正系数-Use white balance algorithm matlab realize, the the detection image bright spot as the ideal white point, calculate the correction factor

图像中较小的亮点检测，利用在二值图像中，进行八邻域寻找的方法，能找到高亮点的具体位置，并框出(Small window in the image detection, the use in binary image, the eight neighborhood search method, can find the location of the high window, and the box)
