Parameter-free modelling of 2D shapes with ellipses
作者：
Highlights：
• 2D shape representation with an automatically determined number of ellipses.
• We propose a novel definition of shape complexity that exploits the shape skeleton.
• Good balance between model complexity and shape coverage.
• Experiments on more than 4000 2D shapes show the effectiveness of the proposed methods.
• The solutions proposed by AEFA and DEFA seem to agree with human intuition.
