Cutpicture(form)做的是直方图统计:
第一步:读入图片,并将彩色图片用公式转化为灰度图像。
第二步:用区域生长法将图片分块并对每一块做直方图统计,用广度优先搜索完成,子程序是int flood_fill()。返回值是区域内的点的数量。判断是否属于同一块区域的条件是前面搜索得到的灰度平均值是否大于给定阈值(即threshold,由用户输入决定)。
第三步:任意两块区域对区域直方图的每个色阶比例的差的绝对值求和,若和小于阈值(即threshold2,由用户输入决定)则合并两

区域生长算法被证实是一个有效的图像分割方法。区域生长的基本方法是从被分割对象
里作为种子区域(通常是一个或多个像素)的一个区域开始,在种子区域的相邻像素寻找与种
子像素有相同或相似性质的像素,并将这些像素合并到种子像素所在的区域中。将这些新像
素当作新的种子区域继续进行上述过程。区域生长算法主要取决于用来选择确定为种子区域
像素的标准、用来确定相邻像素的连通性类型和用来访问相邻像素的策略。-Region growing algorithms have proven to be a
