Local cosine bases in two dimensions

Research output: Contribution to journalConference article


We construct two-dimensional local cosine bases in discrete and continuous time. Solutions are offered both for rectangular and nonrectangular lattices. In the case of nonrectangular lattices, the problem is solved by mapping it into a one-dimensional equivalent problem.
