图像识别路面裂缝识别含GUI源码

Posted 2021-05-18 Matlab走起

数学形态学操作可以分为二值形态学和灰度形态学，灰度形态学由二值形态学扩展而来。数学形态学有2个基本的运算，即腐蚀和膨胀，而腐蚀和膨胀通过结合又形成了开运算和闭运算。
开运算就是先腐蚀再膨胀，闭运算就是先膨胀再腐蚀。

• 二值形态学

粗略的说，腐蚀可以使目标区域范围“变小”，其实质造成图像的边界收缩，可以用来消除小且无意义的目标物。式子表达为：

该式子表示用结构B腐蚀A，需要注意的是B中需要定义一个原点，【而B的移动的过程与卷积核移动的过程一致，同卷积核与图像有重叠之后再计算一样】当B的原点平移到图像A的像元(x,y)时，如果B在（x,y）处，完全被包含在图像A重叠的区域，(也就是B中为1的元素位置上对应的A图像值全部也为1)则将输出图像对应的像元(x,y)赋值为1，否则赋值为0。
我们看一个演示图。

B依顺序在A上移动（和卷积核在图像上移动一样，然后在B的覆盖域上进行形态学运算），当其覆盖A的区域为[1,1;1,1]或者[1,0;1,1]时，（也就是B中‘1’是覆盖区域的子集）对应输出图像的位置才会为1。

• 膨胀

粗略地说，膨胀会使目标区域范围“变大”，将于目标区域接触的背景点合并到该目标物中，使目标边界向外部扩张。作用就是可以用来填补目标区域中某些空洞以及消除包含在目标区域中的小颗粒噪声。

该式子表示用结构B膨胀A，将结构元素B的原点平移到图像像元(x,y)位置。如果B在图像像元(x,y)处与A的交集不为空（也就是B中为1的元素位置上对应A的图像值至少有一个为1），则输出图像对应的像元(x,y)赋值为1，否则赋值为0。
演示图为：

function varargout = Gui_Main(varargin)
% GUI_MAIN M-file for Gui_Main.fig
%      GUI_MAIN, by itself, creates a new GUI_MAIN or raises the existing
%      singleton*.
%
%      H = GUI_MAIN returns the handle to a new GUI_MAIN or the handle to
%      the existing singleton*.
%
%      GUI_MAIN('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in GUI_MAIN.M with the given input arguments.
%
%      GUI_MAIN('Property','Value',...) creates a new GUI_MAIN or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Gui_Main_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to Gui_Main_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
