🔹 Brainweb MRI Simulator

✔ Provides realistic MRI data volumes generated by an MRI simulator.

✔ Used for validating neuroimaging analysis methods where the ground truth is known.

🔹 N3 (Non-Parametric Non-Uniformity Normalization)

✔ Corrects intensity non-uniformity in MRI scans caused by field inhomogeneities.

✔ Essential preprocessing step in most MRI analysis pipelines.

🔹 BEaST (Brain Extraction based on nonlocal Segmentation Technique)

✔ Multi-resolution patch-based method for skull stripping and brain extraction.

✔ Produces highly accurate brain masks, improving tissue segmentation reliability.

🔹 INSECT (Intensity-Normalized Stereotaxic Environment for Classification of Tissues)

✔ Segments structural MRI scans into white matter, gray matter, and CSF.

✔ Available in the classify package.
