Matlab实现SeamCarving算法 放大缩小图片(包含GUI)

function varargout = SeamCutGUI(varargin) % SEAMCUTGUI M-file for SeamCutGUI.fig % SEAMCUTGUI, by itself, creates a new SEAMCUTGUI or raises the existing % singleton*. % % H = SEAMCUTGUI returns the handle to a new SEAMCUTGUI or the handle to % the existing singleton*. % % SEAMCUTGUI('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in SEAMCUTGUI.M with the given input arguments. % % SEAMCUTGUI('Property','Value',...) creates a new SEAMCUTGUI or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before SeamCutGUI_OpeningFunction gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to SeamCutGUI_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)". % % See also: GUIDE, GUIDATA, GUIHANDLES % Edit the above text to modify the response to help SeamCutGUI % Last Modified by GUIDE v2.5 18-Dec-2007 18:51:51 % Author: Danny Luong % http://danluong.com % % Last updated: 12/20/07 % Begin initialization code - DO NOT EDIT gui_Singleton = 1; gui_State = struct('gui_Name', mfilename, ...
