We deal with the Fourier-like analysis of functions on discrete grids in two-dimensional simplexes using C-and E-Weyl group orbit functions. For these cases, we present the convolution theorem. We provide an example of application of image processing using the C-functions and the convolutions for spatial filtering of the treated image.
