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 transformation parameters are specified by the user by editing the　values of the rotation, scale (x and y), and shear (x and y).
