% ****************************************************** % % time : 2021/05/26 17:12 % tip : 车牌识别 % change: % ******************************************************* function varargout = CarId(varargin) % CARID MATLAB code for CarId.fig % CARID, by itself, creates a new CARID or raises the existing % singleton*. % % H = CARID returns the handle to a new CARID or the handle to % the existing singleton*. % % CARID('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in CARID.M with the given input arguments. % % CARID('Property','Value',...) creates a new CARID or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before CarId_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to CarId_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
