Fast interpolation for line-pruned images
Anh Vu Le, Hye-moon Kim, Chee-Sun Won · Journal of Electronic Imaging · 2011
An interpolation method for a line-pruned image is presented. The goal is to alleviate the time complexity of the previous NEDI-8 (new edge directed interpolation) method. The idea of our solution is to use NEDI-4 selectively, applying the NEDI-4 for edge pixels while using a linear filter for others. For the linear filter, the interpolation coefficients for each pruned line are adaptively determined.
