Abstract landscape

Our idea is to placing interesting curves to abstract an image.  The novelty comes from the introduction of new primitive in image abstraction.
2. The proposed algorithms:
(1) draw curves along edge directions. Curves properties include length, the error to the directional filed, color, thickness, and the depth.
(2) determine the quality and the number of curves used
(3) Test different depth of each curve

Goal: The final placement should represent the image content in some way. Aesthetics may be more important than structural preservation.

Issues:
(1) curve generations: a curve could grow along a field.
a. the old particle system for the artistic tessellation paper; or b. the spiral curve
(2) the objective of the quality
This is hard. This matters when to stop the process.
