EdgeBlur node

This documentation is for version 1.0 of EdgeBlur.


Blur the image where there are edges in the alpha/matte channel.


Input Description Optional
Source   No
Mask   Yes
Matte   Yes


Parameter / script name Type Default Function
Convert to Group / convertToGroup Button   Converts this node to a Group: the internal node-graph and the user parameters will become editable
R / Blur1NatronOfxParamProcessR Boolean On  
G / Blur1NatronOfxParamProcessG Boolean On  
B / Blur1NatronOfxParamProcessB Boolean On  
A / Blur1NatronOfxParamProcessA Boolean On  
External Matte / externalMatte Boolean Off Use the edges from the Matte input instead of the alpha channel of the source image.
Size / size Double 3  
Filter / filter Choice Gaussian

Simple: Gradient is estimated by centered finite differences.
Sobel: Compute gradient using the Sobel 3x3 filter.
Rotation Invariant: Compute gradient using a 3x3 rotation-invariant filter.
Quasi-Gaussian: Quasi-Gaussian filter (0-order recursive Deriche filter, faster) - IIR (infinite support / impulsional response).
Gaussian: Gaussian filter (Van Vliet recursive Gaussian filter, more isotropic, slower) - IIR (infinite support / impulsional response).
Box: Box filter - FIR (finite support / impulsional response).
Triangle: Triangle/tent filter - FIR (finite support / impulsional response).
Quadratic: Quadratic filter - FIR (finite support / impulsional response).
Crop To Format / cropToFormat Boolean On  
Edge Mult / edgeMult Double 2 Sharpness of the borders of the blur area.
Invert Mask / Merge1maskInvert Boolean Off  
Mix / Blur1mix Double 1
