Joint edge-directed interpolation and adaptive sharpening filter


In this paper, we present a joint filter that upsamples and adaptively sharpens a video/image simultaneously. The joint filter has been designed by combining a low complexity edge-directed interpolator with an adaptive Laplacian of Gaussian (LoG) filter. The joint filter yields sharp upsampled images, and is demonstrated to have lower computational complexity and similar visual quality when compared to using separate upsampling and sharpening filters.
