Directional Cubic Convolution Interpolation, sep = separator()

Author: Garagecoder. Latest update : 2015/11/07.


This filter re-implements the scaling algorithm described at :

wikipedia.org: https://en.wikipedia.org/wiki/Directional_Cubic_Convolution_Interpolation

The algorithm is intended for enlarging images while avoiding

artifacts, e.g. staircase artifacts.

Threshold controls edge[lower to texture[higher balance.

Exponent controls texture edge sharpness[higher.

Warning: highly experimental…

Wrapper for the G’MIC framework (http://gmic.eu) written by Tobias Fleischer (http://www.reduxfx.com).
