Euclidean and XOR
MPEG-7 3D Shape Spectrum Descriptor Euclidean
Depthmap

• The first metric 'Euclidean and XOR'is used for our descriptor (VMBA) which encodes the body and the appendages of a vessel into two vectors.

• The next one is referred to the MPEG-7 3D Shape Spectrum Descriptor (A 64 bin signature has been used)

• The 'Depthmap' option represents a descriptor named CBDM (Character Based Depthmap Encoding) which encodes two depthmap images of the vessel into character sequences. The Needleman-Wunsch algorithm is used for shape matching. This descriptor is a variant of the M. Chaouch, A. Verroust-Blondet, A New Descriptor for 2D Image Indexing and 3D Model Retrieval, in Procs. of ICIP 2007
