Hierarchical edge-directed interpolation for de-interlacing
Fan Zhai · 2011
High quality motion-adaptive de-interlacing calls for high quality spatial interpolation that can generate smooth object edges without jaggy effects. In this paper, we present a hierarchical edge-directed interpolation, where the edge detection not only covers very wide range of angles but also provides high resolution edge vectors. In addition, the hierarchical architecture makes it highly efficient for hardware implementation.
