appropriate coefficients for the warping. Besides changing the shape of the image
using warping, morphing also interpolates the intensities of the two images using
alpha blending, see Sect. 4.6.
As mentioned above an endless number of different effects can be created based
on pixel manipulation and/or geometric transformations. In Fig. 11.16 the effects of
nine additional methods are illustrated.
