Description: ex4.14 图元识别问题« 问题描述：在数字化图像处理中常将一幅图像表示为一个m´ m 的像素矩阵。其中每个像素的值为0或1。值为0的像素表示图像的背景，而值为1 的像素表示图像中某个图元上的一个点，通常称其为图元像素。当一个像素在另一个像素的上方、下方、左侧或右侧时，称这2个像素为相邻像素。一幅图像中的相邻像素属于同一图元，而不相邻的像素属于不同图元。图元识别问题就是对给定图像的图元像素进行标记，使得同一图元的图元像素有相同的标记，而不同图元的图元像素其标记也不同。试用抽象数据类型队列设计解图元识别问题的算法，并分析算法的计算复杂性。« 数据输入：由文件input.txt给出输入数据。第一行有1 个正整数m，表示给定m´ m的像素矩阵。接下来的m行中，每行m个数，表示m个像素，值为0 的像素表示图像的背景，而值为1的像素表示图像中某个图元上的一个点。« 结果输出:将计算出的不同图元的个数输出到文件output.txt。输入文件示例 输出文件示例input.txt output.txt70 0 1 0 0 0 00 0 1 1 0 0 00 0 0 0 1 0 00 0 0 1 1 0 01 0 0 0 1 0 01 1 1 0 0 0 01 1 1 0 0 0 03-ex4.14 map identification laquo yuan; Problem description : the digital image processing of an image often expressed as a macute; M pixel matrix.
