Paper Abstract

Upsampling is a post-processing method for increasing the spatial resolution of an image or video. Most video players and image viewers support upsampling functionality. Sometimes upsampling can introduce blurring, ringing, and jaggedness artifacts in the upsampled video or image thereby lowering its visual quality. In this paper, we present an adaptive bilateral interpolation filter for upsampling a video or image by an arbitrary upsampling factor, and show that it mitigates most of the artifacts produced by conventional upsampling methods.
