Paper Abstract

Image interpolation using non-linear approaches is investigated in this paper. We shall study this problem by concentrating on two sub-sampling schemes that are most commonly adopted in practice: (1) quincunx lattice and (2) every other row and every other column (EORC) lattice. For each sub-sampling lattice, we propose four interpolation structures and compare them by considering the computational complexity and testing with both natural and synthetic images. Comparisons of the proposed non-linear interpolators with some linear approaches are also presented. With the results obtained in this paper, we can come out with a general conclusion that the non-linear interpolation should be preferred to in practice.
