1 简介
大米是人类的主食之一，是稻谷经清理、砻谷、碾米、成品整理等工序后制成的成品。人们购买米大多采用直接称量的方法，市面上也有许多仪器采用光电传感器等方式用于生产加工时米粒的计数。然而这样的方法都比较依赖于设备，不方便人们日常的使用。运用计算机图像处理技术，可以在缺少专用设备的情况下，快速简单地完成对米粒或其他颗粒的计数。

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