基于灰度直方图的水果识别系统开发：MATLAB源代码及图形用户界面设计

一、简介

基于matlab GUI 灰度、二值化、腐蚀、直方图处理之水果识别

二、源代码

function varargout &＃61; untitled(varargin)
% UNTITLED MATLAB code for untitled.fig
% UNTITLED, by itself, creates a new UNTITLED or raises the existing
% singleton*.
%
% H &＃61; UNTITLED returns the handle to a new UNTITLED or the handle to
% the existing singleton*.
%
% UNTITLED(&＃39;CALLBACK&＃39;,hObject,eventData,handles,...) calls the local
% function named CALLBACK in UNTITLED.M with the given input arguments.
%
% UNTITLED(&＃39;Property&＃39;,&＃39;Value&＃39;,...) creates a new UNTITLED or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before untitled_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to untitled_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE&＃39;s Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
