Bi-Cubic Interpolation Algorithm for Image Scaling

The bitap algorithm (also known as the shift-or, shift-and or Baeza-Yates–Gonnet algorithm) is an approximate string matching algorithm. The algorithm tells whether a given text contains a substring which is "approximately equal" to a given pattern, where approximate equality is defined in terms of Levenshtein distance – if the substring and pattern are within a given distance k of each other, then the algorithm considers them equal. The algorithm begins by precomputing a set of b… Web1 Answer. You have to loop over destination pixels instead of source ones (gaps are the result of looping over source).
