- Published 2006

The discrete triangle transform (DTT) was recently introduced [1] as an example of a non-separable transform for signal processing on a two-dimensional triangular grid. The DTT is built from Chebyshev polynomials in two variables in the same way as the DCT, type III, is built from Chebyshev polynomials in one variable. We show that, as a consequence, the… CONTINUE READING
