系统对进入停车位的车辆进行车牌识别，将识别出来的车牌号显示出来；然后对车主进行人脸识别，框出车主照片的人脸部分作为车主信息的标记，记录在系统库中。车辆在库期间，系统使用者可以随意查看车辆与车主信息的获取过程及获取结果，当驾驶车辆离开停车场时，系统库将清空该车辆与车主的信息。

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