matlab_各种分割算法的实验 包括阈值分割，多阈值分割，二维最大熵分割

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