Curve normalization for shape retrieval

作者：

Highlights：

• Polygonal approximation is used for outline decomposition.

• Each part is approximated by the Least squares model.

• The obtained curves are normalized.

• A scheme technique for curves similarity is defined to establish shape similarity.
