Image Filtering GUI

by

 

A GUI that converts image,blur image, filter image and also write(save) the image into a disk as jpg

image_processing2(varargin)
function varargout = image_processing2(varargin)
% IMAGE_PROCESSING2 M-file for image_processing2.fig
%      IMAGE_PROCESSING2, by itself, creates a new IMAGE_PROCESSING2 or raises the existing
%      singleton*.
%
%      H = IMAGE_PROCESSING2 returns the handle to a new IMAGE_PROCESSING2 or the handle to
%      the existing singleton*.
%
%      IMAGE_PROCESSING2('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in IMAGE_PROCESSING2.M with the given input arguments.
%
%      IMAGE_PROCESSING2('Property','Value',...) creates a new IMAGE_PROCESSING2 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before image_processing2_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to image_processing2_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
