1、 数字图像处理课程设计报告题 目： 简单图像处理系统 专 业： 信息与计算科学 学 号： 0 组 长： 指导教师： 成 绩： 二一 年 六 月 二十六 日一、课程设计目的课程设计的目的是训练我们学生应用所学数字图像处理知识，完成题目分析、编程实现等软件开发全过程的综合实践能力。巩固、深化学生的理论知识，提高编程水平，并在此过程中培养我们严谨的科学态度和良好的工作作风。二、课程设计基本要求1、对知识点的掌握要求：（1）熟悉数字图像处理的概念，特点及应用（2）掌握数字图像处理处理过程及问题的分析与纠正（3）利用C+对确定对图像处理分析（4）学会C+的使用，掌握C+的程序设计方法2、分组情况：组长：

2、 组员 ：设计全过程的监督及协助、部分源程序代码的编写和整个源程序代码的整理。：编写右边直方图Panel的代码：编写主程序并运行：编写左边直方图Panel的代码：结果分析部分及查找相关文献3、课程设计内容以确定处理分析的对象，进行编程来实现这一过程。三、课程设计实现步骤1、问题描述先对图像进行分析，从而编写主程序，编写右边直方图Panel的代码，再编写左边直方图Panel的代码，从而运行出如结果分析中的图像。2、主程序如下：package dege.imagetool;import java.awt.BorderLayout;import java.awt.FlowLayout;import
