Abstract
Double interpolation quality evaluation can be used as a measurement of an interpolation operation. By using this double interpolation framework, a high efficient direction-adaptive upsampling algorithm is proposed without any threshold setting and post-processing. With the proposed upsampling algorithm, the problem of zigzagging artifacts on the edge no longer exists. Moreover, the proposed algorithm has low computation complexity. The experimental results show that the proposed algorithm has high quality image output.
