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.
