Paper Abstract:	This paper summarizes the edge-directed image upsampling method based on radial basis function (RBF) interpolation [5] and discusses a new kernel based interpolation method. The resampling evaluation is determined according to the edge orientation. The proposed scheme is as simple to implement as linear methods but it demonstrates improved visual quality by preserving the edge features better than the classical linear interpolation methods. The algorithm is compared with some well-known linear schemes as well as recently developed nonlinear schemes.
