A Novel Adaptive Directional Interpolation Algorithm for Digital Video Resolution Enhancement

Algorithm 1:

Main direction searching

Partition f into overlapping patches , and for each patch, do the following steps:

  • Initialization: Set main direction angle set , candidate angle set , the largest number of direction angles . Set start point .

  • Main loop (repeat times):

    - Calculate the filtering result ;

    - Find the best angle ;

    - Update , and for the next iteration.

  • Output: The main direction angle set S of the th image patch .
