File Information
Description

AffineTransformation 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 the image by
 subtracting the shape cetroid.
 The affine matrix and the affinr transformation are computed using Matlab Image Processing Toolbox
 functions: maketform and imtransform. So this program is only demonstrates and facilitates the computation and the applying of these functions to a 2-D image.

The first argument (STRING) must be a one-dimensional array of char or cell arrays of
strings.

Error in ==> AffineTrnasformation>Save_image_Callback at 408
g=regexpi(valid_ex,p); % Match Exact extension, ignoring case.

Really useful if you need a fast transformation

It works very well.

Very Good

To everyone who want to use and rate this function:
Could you pleasse check the matlab version before downloading the files?, becuase it will not work on older versions. I find it unfair to rate a function while the error is from your side.

it is not working,
??? Undefined function or variable 'gui_mainfcn'.

Error in ==> G:\thesis\matlab\AffineTransformation.m
On line 38 ==> gui_mainfcn(gui_State, varargin{:});

Well enough!

It is not working, the error is Reference to non-existent field 'Showaxes'.
