Feature Forest

A napari plugin for making image annotation using feature space of vision transformers and random forest classifier.
We developed a napari plugin to train a Random Forest model using extracted features of vision foundation models and just a few scribble labels provided by the user as input. This approach can do the segmentation of desired objects almost as well as manual segmentations but in a much shorter time with less manual effort.
