My previous work compares efficiency of two shape models: the Blum medial axis, which is a skeletal shape model, and the boundary curve. Results are presented in three papers, in which we compute the epsilon-entropy of classes of plane curves, compare adaptive approximation using the two shape models including an application of results to a large shape databse, and compare uniform encoding using the two shape models.

boundary curve, Int. J. Comp. Vis., 74, 2007, 183 - 199.
3. Comparison for uniform encoding.

My current work aims to construct results similar to those presented in the above papers using a more general medial structure developed by Damon and Pizer.
