Contour-based Images: Representation, Creation and Manipulation
This thesis proposes a novel image primitive - the diffusion curve.
This primitive relies on the principle that images can be defined via
their discontinuities, and concentrates image features along contours.
The diffusion curve can be defined in vector graphics, as well as in
raster graphics, to increase user control during the process of art
creation.
The vectorial diffusion curve primitive augments the expressive powers
of vector images by capturing complex spatial appearance behaviors.
Diffusion curves represent a simple and easy-to-manipulate support for
complex content representation and edition.
In raster images, diffusion curves define a higher level structural
organization of the pixel image. This structure is used to create
simplified or exaggerated representations of photographs in a way
consistent with the original image content. Finally, a fully automatic
vectorization method is presented, that converts raster diffusion curve
to vector diffusion curve.
