一、簡介
現在商業行為中,在水果出廠前都需要進行質量檢測,需要將不同等級的水果進行分級包裝,以保證商業利益最大化。可是傳統方法都是依靠人工進行檢測,效率低下,主觀成分大,并不能很好客觀地評價出貨質量,導致工廠損失利益水果檢測儀水果檢測儀,增加客戶投訴,從而造成品牌效率損失乙炔檢測儀,造成隱形的損失。
該課題為基于MATLAB的水果分級系統。適用圓形水果,如蘋果酒精檢測儀,橘子水果檢測儀,柚子,柿子等,統計水果圖片的面積,圓形度和色澤等多參數進行評價。該設計帶一個GUI界面,通過設置直徑和色澤,測試水果的這些參數,從而得出該水果所屬等級。
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)".
