Abstract:
In this paper, we present an example-based facial sketch
system. Our system automatically generates a sketch from
an input image, by learning from example sketches drawn
with a particular style by an artist. There are two key elements
in our system: a non-parametric sampling method
and a flexible sketch model. Given an input image pixel and
its neighborhood, the conditional distribution of a sketch
point is computed by querying the examples and finding
all similar neighborhoods. An “expected sketch image” is
then drawn from the distribution to reflect the drawing style.
Finally, facial sketches are obtained by incorporating the
sketch model. Experimental results demonstrate the effectiveness
of our techniques.
