Abstract :
A form of the two-dimensional (2D) DFT, robust with respect to the influence of impulse noise, is defined. Different forms of the robust 2D DFT based on the iterative procedures and various median filter forms are introduced. The realization based on the robust 1D DFT along one coordinate and standard 1D DFT along the other one is also proposed. It performs similarly to other robust 2D DFT forms with significant calculation savings.
