Gabor Filter – Fine Hair Extraction v2.0 Nuke gizmo is a free plugin for The Foundry’s Nuke digital compositing software. It is designed to automatically detect and extract fine hairs from images and footage. The plugin utilizes Gabor filters to detect and extract fine hairs from the input image. It is useful for post-production tasks such as creating clean plates for compositing, relighting, color grading, and more.
Keying fine hair has never been easier!
The node outputs the filtered image in the 3 RGB channels. A strong contrast on the source image will give stronger, better results. If you’re using it on a green screen for hair extraction, you generally will use the green channel only as it is the one with the strongest contrast between the strands and the background.
Then, you can use a “merge” node with operation “plus” to add the hair details to your existing alpha (IBK or anything else).
