Hybrid interpolation algorithm for reconstruction of sub-sampled chrominance components

This paper proposes a hybrid interpolation algorithm for reconstruction of chrominance components to original resolution which are sub-sampled as 4-2-0 format. The proposed approach combines a simple interpolation method with a more complex one. It adaptively selects the most appropriate interpolation method for a given pixel position using our own decision criteria in order to provide high-quality images while reducing the complexity efficiently.
