基于MATLAB GUI手指指尖检测
一、简介
基于matlab GUI手指指尖的图像采集与检测，可以作为手势识别和石头剪刀布的基础课题。
二、源代码
function varargout = hands(varargin)
% HANDS MATLAB code for hands.fig
% HANDS, by itself, creates a new HANDS or raises the existing
% singleton*.
%
% H = HANDS returns the handle to a new HANDS or the handle to
% the existing singleton*.
%
% HANDS('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in HANDS.M with the given input arguments.
%
% HANDS('Property','Value',...) creates a new HANDS or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before hands_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to hands_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
