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