水果识别基于matlab GUI柑橘质量检测及分级系统含Matlab源码 738期

一、简介

现在商业行为中，在水果出厂前都需要进行质量检测，需要将不同等级的水果进行分级包装，以保证商业利益最大化。可是传统方法都是依靠人工进行检测，效率低下，主观成分大，并不能很好客观地评价出货质量，导致工厂损失利益，增加客户投诉，从而造成品牌效率损失，造成隐形的损失。
该课题为基于MATLAB的水果分级系统。适用圆形水果，如苹果，橘子，柚子，柿子等，统计水果图片的面积，圆形度和色泽等多参数进行评价。该设计带一个GUI界面，通过设置直径和色泽，测试水果的这些参数，从而得出该水果所属等级。

二、源代码

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