abstract = {A skeletal stroke is a kind of general brush stroke for changing
the shape of pictures as if by bending, shearing, twisting, while
conservating the aspect ratio of selected features on tie picture.
It is neither a simple warping nor texture mapping technique, but
a new method for controlling the deformation of a picture. A
deformation model of a cocJrdinate system has been proposed taking
into account cases of discontinuous or extreme bending.
Complicated pictures can be built up hierarchically by defining
higher order strokes and recursive strokes. It is therefore a
powerful general drawing tool and extended image transformation
instrument. The use of skeletal strokes as a replacement for
affine transformations in IFS coding has been explored. A novel
general anchoring mechanism is proposed, which allows arbitrary
control of any point in the picture. This control flexibility is
particularly desirable in computer animation and digital
typography. As a result, virtual "2-D models" of cartoon
characters as well as pseudo 3-D objects can be created and
manipulated with ease.},
