datagh1.m

本程序是对一幅图像进行变灰度、旋转、锐化、在图像上画圆或椭圆、直线等操作的程序。 说明：要实现相应功能的操作

function varargout = datagh1(varargin)
% DATAGH1 M-file for datagh1.fig
%      DATAGH1, by itself, creates a new DATAGH1 or raises the existing
%      singleton*.
%
%      H = DATAGH1 returns the handle to a new DATAGH1 or the handle to
%      the existing singleton*.
%
%      DATAGH1('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in DATAGH1.M with the given input arguments.
%
%      DATAGH1('Property','Value',...) creates a new DATAGH1 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before datagh1_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to datagh1_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
