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