Landmarks inside the shape: Shape matching using image descriptors
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.
