abstract = {This dissertation presents: a method for creating black-and-white
illustrations and caricatures of human faces from source
photographs; and series of perceptual studies aimed at evaluating
the effectiveness of the resulting images relative to photographs.
The illustrations are generated by superimposing two images: a
thresholded image of the output of a computational brightness
model, and a thresholded luminance image. In addition, a new
interactive technique is demonstrated for deforming images of
faces to create caricatures that highlight and exaggerate
representative facial features. The photographs and
black-and-white illustrations are evaluated via psychophysical
studies to assess speed and accuracy in learning and recognition
tasks. These studies show that the facial illustrations and
caricatures generated using these techniques are as effective as
photographs in the recognition tasks. In the learning studies,
tasks involving illustrations or caricatures were performed
significantly faster than the same tasks were performed with
photographs. The recognition invariance effect is used as an
experimental probe in a functional magnetic resonance imaging
(fMRI) experiment. The results of this experiment indicate that
viewers may process illustrations differently from photographs.},
