图像分割就是把图像分成若干个特定的、具有独特性质的区域并提出感兴趣目标的技术和过程。它是由图像处理到图像分析的关键步骤。现有的图像分割方法主要分以下几类:基于阈值的分割方法、基于区域的分割方法、基于边缘的分割方法以及基于特定理论的分割方法等。从数学角度来看，图像分割是将数字图像划分成互不相交的区域的过程。图像分割的过程也是一个标记过程，即把属于同一区域的像素赋予相同的编号。

- function varargout = ImageGUI(varargin)
- % IMAGEGUI MATLAB code for ImageGUI.fig
- % IMAGEGUI, by itself, creates a new IMAGEGUI or raises the existing
- % singleton*.
- %
- % H = IMAGEGUI returns the handle to a new IMAGEGUI or the handle to
- % the existing singleton*.
- %
- % IMAGEGUI('CALLBACK',hObject,eventData,handles,...) calls the local
- % function named CALLBACK in IMAGEGUI.M with the given input arguments.
- %
- % IMAGEGUI('Property','Value',...) creates a new IMAGEGUI or raises the
- % existing singleton*. Starting from the left, property value pairs are
- % applied to the GUI before ImageGUI_OpeningFcn gets called. An
- % unrecognized property name or invalid value makes property application
- % stop. All inputs are passed to ImageGUI_OpeningFcn via varargin.
