 This results in the so-called combined DFT/LDE filtering technique in which the Discrete Fourier Transform is performed in some of the dimensions prior to Linear Difference Equation filtering which is performed later in the remaining dimensions.Such kind of filtering of M-D signals is referred to as Mixed domain(MixeD) filtering and the filters that perform such kind of filtering are referred to as MixeD Multidimensional Filters.Combining Discrete Transforms with Linear Difference Equations for implementing the Multidimensional filters proves to be computationally efficient and straightforward to design with low memory requirements for spatio-temporal applications such as video processing.
