In this paper, we construct two-dimensional (2D) FIR paraunitary Cosine Modulated Filter Banks (CMFB). All the analysis and synthesis filters are cosine-modulated versions of a 2D non-separable prototype; each filter consists of two shifts of the prototype. The design of the filter bank involves only the optimization of the prototype. Furthermore, the complexity of the 2D filter bank is that of the prototype plus two non-separable DCT matrices.
