一、簡(jiǎn)介
現(xiàn)在商業(yè)行為中,在水果出廠前都需要進(jìn)行質(zhì)量檢測(cè),需要將不同等級(jí)的水果進(jìn)行分級(jí)包裝,以保證商業(yè)利益最大化。可是傳統(tǒng)方法都是依靠人工進(jìn)行檢測(cè),效率低下,主觀成分大,并不能很好客觀地評(píng)價(jià)出貨質(zhì)量,導(dǎo)致工廠損失利益水果檢測(cè)儀水果檢測(cè)儀,增加客戶投訴,從而造成品牌效率損失乙炔檢測(cè)儀,造成隱形的損失。
該課題為基于MATLAB的水果分級(jí)系統(tǒng)。適用圓形水果,如蘋果酒精檢測(cè)儀,橘子水果檢測(cè)儀,柚子,柿子等,統(tǒng)計(jì)水果圖片的面積,圓形度和色澤等多參數(shù)進(jìn)行評(píng)價(jià)。該設(shè)計(jì)帶一個(gè)GUI界面,通過(guò)設(shè)置直徑和色澤,測(cè)試水果的這些參數(shù),從而得出該水果所屬等級(jí)。
二、源代碼
function varargout = appletest(varargin)
% APPLETEST MATLAB code for appletest.fig
% APPLETEST, by itself, creates a new APPLETEST or raises the existing
% singleton*.
%
% H = APPLETEST returns the handle to a new APPLETEST or the handle to
% the existing singleton*.
%
% APPLETEST('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in APPLETEST.M with the given input arguments.
%
% APPLETEST('Property','Value',...) creates a new APPLETEST or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before appletest_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to appletest_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
