G’MIC Upscale DCCI2x node — Natron 2.5.0 documentation

# G’MIC Upscale DCCI2x node

This documentation is for version 1.0 of G’MIC Upscale DCCI2x (eu.gmic.UpscaleDCCI2x).

## Description

Directional Cubic Convolution Interpolation

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

Note: 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) and Frederic Devernay.
