图像处理基于matlab自动报靶系统（重弹孔）

Posted 2021-06-28 MatlabQQ1575304183

一、简介

图像处理-形态学

数学形态学的基本思想是用具有一定形态的结构元素去度量和提取图像中的对应形状以达到对图像分析和识别的目的。数学形态学的基本运算有四个：腐蚀、膨胀、开和闭。基于这些基本运算还可以推导和组合成各种数学形态学实用算法。本实验分别实现针对二值图像和灰度图像的四种形态学操作。

一、二值图像的腐蚀、膨胀、开、闭操作

 

二、灰度图像的腐蚀、膨胀、开、闭操作

 

二、源代码

% SHOOT_SYSTEM M-file for shoot_system.fig

                   'gui_LayoutFcn',  [] , ...
                   'gui_Callback',   []);
if nargin && ischar(varargin{1})
    gui_State.gui_Callback = str2func(varargin{1});
end
