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