(eng): This paper deals with moment invariants with respect to image blurring. It is mainly a reaction to the works of Zhang et al. and Chen et al., recently published in these Transactions. We present a generalmethod on how to construct blur invariants from arbitrary moments and show that it is no longer necessary to separately derive the invariants for each polynomial basis. We show how to discard dependent terms in blur invariants definition and discuss a proper implementation of the invariants in orthogonal bases using recurrent relations. An example for Legendre moments is given.
