The Fetal Tissue Annotation and Segmentation Challenge (FeTA) is a multi-class, multi-institution image segmentation challenge part of MICCAI 2022. The goal of FeTA is to develop generalizable automatic multi-class segmentation methods for the segmentation of developing human brain tissues that will work with data acquired at different hospitals. This document is the supplementary information corresponding to the FeTA 2022 Challenge Results paper (https://arxiv.org/abs/2402.09463). This document contains the methods descriptions of each submission to FeTA 2022, as well as the detailed ranking reports for the challenge results.
