Translation invariants of modified Chebyshev moments

The translation invariants of moments based on polynomials can be achieved by many methods, such as geometric moments, Legendre moments, and so on. In this paper, based on the modified discrete Chebyshev polynomials, the modified discrete Chebyshev moments, which can remain invariant for translated images and are superior to classical Chebyshev moments in the aspect of representation capability, is proposed. And the performance of the proposed descriptors is experimentally verified by using a set of binary English, Chinese characters as well.
