STAPLE
The STAPLE node implements the Simultaneous Truth and Performance Level Estimation algorithm for generating ground truth volumes from a set of binary expert segmentations.
The STAPLE algorithm treats segmentation as a pixelwise classification, which leads to an averaging scheme that accounts for systematic biases in the behavior of experts in order to generate a fuzzy ground truth volume and simultaneous accuracy assessment of each expert. The ground truth volumes produced by this filter contain values between zero and one that indicate probability of each pixel being in the object targeted by the segmentation.
Inputs
Inputs
Input list of masks containing segmentations of the same object. Must contain at least two masks of the same size.
