具体实现三维图像的仿射变换

function varargout = AffineTrnasformation(varargin)
% AFFINETRNASFORMATION M-file for AffineTrnasformation.fig
% Affine_Transf computes and applies the geometric affine transformation to a 2-D image.
%
% The program main functions are:
% - Load Image: Load the image to be transformed.
% - Transform Image: Computes the transformation matrix from the transformation parameters specified by the user, then it applies the transformation to the loaded image.
% - Save Image: Save the transformed image.
% - Quit: Exit the program.
% The transformation parameters are specified by the user by editing the
% values of the rotation, scale (x and y), and shear (x and y). The
% translation is not icluded because it can be easily (normalized or) removed from image by
% subtracting the shape cetroid.
%
% The affine matrix and the transformation are computed using Matlab Image Processing Toolbox
% functions: maketform and imtransform, so this program is only demonstrates the computation and the applying of these functions to a 2-D image.
