Euler vector: a combinatorial signature for gray-tone images
Proceedings. International Conference on Information Technology: Coding and Computing
A new combinatorial characterization of a gray-tone image called Euler Vector is proposed. Euler number of a binary image is a well-known topological feature, which remains invariant under translation, rotation, scaling, and rubber-sheet transformation of the image. Euler vector comprises of a 4-tuple, where each element is an integer representing the Euler number of the partial binary image formed by the four most significant bit planes of the graytone image.
