Landmarks inside the shape: Shape matching using image descriptors

作者：

Highlights：

• An internal-landmark based planar shape matching scheme is proposed.

• The shape landmarks are obtained using the recently proposed SPEM representation.

• Properties of SPEM that allow the use of image descriptors inside shapes are discussed.

• Statistical evidence indicates that the number of matches can be used as a similarity measure.
