%X This paper presented a novel method to construct blur-invariant moments based on discrete orthogonal Tchebichef moments in order to deal with blur images affected by a centrosymmetric point spread function(PSF).The structure of proposed blur-invariants was very similar to the ones proposed by Flusser et c.and Wee et c.,but the paper's derivation did not involve numerical approximation of continuous integrals and coordinate space transformation.The blur-invariants have better invariance compared with the one...
