A new adaptive subpixel-based downsampling scheme using edge detection
In this paper, a new adaptive subpixel-based downsampling scheme is proposed. Inside this scheme, we take full advantage of subpixels by adaptively choosing the sample directions based on edge information which has not been addressed before. Then, an adaptive filter is designed to suppress color fringing artifacts. Moreover, a good cut-off frequency is derived and deployed in our filter to obtain extra information. Simulation results illustrate that the proposed adaptive subpixel-based downsampling scheme successfully improves the resolution while efficiently removes visible color fringing artifacts.
