  • Abstract
    We show that the main result on eigenpolynomials for two-dimensional (2-D) sinusoidal signals in a recent letter by Li and Cheng (see ibid., vol.5, p.71-3, March 1998) is incorrect, and hence the characterization of 2-D eigenpolynomials is still an open problem. Furthermore, we state a related problem that is also open and hence awaiting a (satisfactory) solution.
