【图像分割】基于迭代阙值选择、最大类间差、区域生长多种算法实现图像分割

1 简介

重点讨论了图像分割法中的阈值研究法,包括迭代阙值选择、最大类间差、区域生长进行了重点分析,用Matlab进行实现并给出了实验结果.

2 部分代码

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