jedypod / SummedAreaTable.cpp
Last active October 19, 2020 20:10
Perform a spatially varying box blur based on an input map. Box blur only for the moment. Uses a summed area table.
/* Create a summed area table in one direction, based on an input image.
In order to create a 2-dimensional summed area table,
you need two copies of the node, the 2nd with col=true
Currently there are issues with precision for higher resolution images...

Image<eRead, eAccessRandom, eEdgeConstant> src;
Image<eReadWrite, eAccessRandom> dst;
jedypod / BoxBlur.cpp
Created October 19, 2020 20:04
Perform a multiple iteration box blur on the input image. Works in a single dimension so 2 copies are needed for a 2 dimensional blur.
/* Perform a horizontal or vertical Box Blur
Can perform multiple iterations in order to approximate a Gaussian Blur.

Distorts an input image based on an input uv map or vector map.

Image<eRead, eAccessPoint, eEdgeClamped> uv;

Nuke blinkscript implementation of a simple image Transform operator. This blinkscript demonstrates pixel filter interpolation algorithms.
Nuke blinkscript implementation of a simple image Transform operator.
Demonstrates pixel filter interpolation algorithms.
The following pixel filters are implemented:
0 - Blackman-Harris : Similar to cubic, but better performance in high frequencies
1 - Lanczos4 : 2x2 lanczos windowed sinc function
2 - Lanczos6 : 3x3 lanczos windowed sinc function
3 - Cubic : (Bicubic interpolation) - a=0.0, b=0.0
4 - Mitchell : (Bicubic interpolation) - a=1/3, b=1/3
