[Image geometry] based on image space transformation (affine transformation) MATLAB source GUI

function varargout = affine_trans(varargin) % AFFINE_TRANS M-file for affine_trans.fig % AFFINE_TRANS, by itself, creates a new AFFINE_TRANS or raises the existing % singleton*. % % H = AFFINE_TRANS returns the handle to a new AFFINE_TRANS or the handle to % the existing singleton*. % % AFFINE_TRANS('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in AFFINE_TRANS.M with the given input arguments. % % AFFINE_TRANS('Property','Value',...) creates a new AFFINE_TRANS or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before affine_trans_OpeningFunction gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to affine_trans_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 affine_trans % Last Modified by GUIDE V2.5 21-May-2009 16:53:05 % Begin initialization code - DO NOT EDIT gui_Singleton = 1; gui_State = struct('gui_Name', mfilename, ...
