Morphing
Morphing is animation that changes one image slowly into another.
It is often used to change one face into another face.
To seamlesly change from one image to another, a series
of points is identified in both the before and after
objects.
This is so major parts will correspond -
e.g., the eyes in a face.
Then the pixels in the first objects are slowly changed into the pixels
in the second object by creating in-between frames with only a few changes
from the previous change.
Warping works with only one object and slowly changes - warps it -
over a series of frames.
