The recent success of high definition screens has increased the need of interpolation algorithms, to display images or videos which resolution is smaller than the screen resolution. We propose a new image interpolation process, based on a multiresolution edge orientation analysis. The goal of this technique is to correct usual artifacts that appear on edges when classical interpolation methods are used (bilinear, bicubic), without introducing new artifacts that are often produced by directional interpolations. Our orientation estimation, based on a quadtree division and a multiresolution approach is evaluated and compared to two other state-of-the-art methods (Radon transform, and the projection method used in the Bandlet transform algorith...
