Brain Mapping Center LONI/SVE Terms of Use Yes UCLA NITRC Segmentation Validation Engine OS Independent Yes The Segmentation Validation Engine (SVE) provides an automated online framework for performing validation studies of skull-stripping methods. Registered users may download 40 T1 MRI volumes, skull-strip them with the algorithm of their choice, and upload their segmentation results to the SVE website (, hosted at the UCLA Brain Mapping Center ( The server will then compare the 40 skull-stripped results against a set of manually generated brain masks. The server computes a series of measures for the uploaded data, including Jaccard and Dice measures, and produces images of the spatial location of segmentation errors relative to a common space. Results are archived on the server, and the measures are viewable by visitors to the site. Details on the methodology can be found in: Shattuck DW, Prasad G, Mirza M, Narr KL, and Toga AW (2009) Online Resource for Validation of Brain Segmentation Algorithms, NeuroImage(doi:10.1016/j.neuroimage.2008.10.066). 2008-11-29 5 - Production/Stable/Mature SVE Segmentation Validation Engine 5 - Production/Stable/Mature, MR, Web Environment, End Users, Developers, LONI/SVE Terms of Use, English, OS Independent, ANALYZE, DICE Coefficient, Tanomoto Coefficient, Web Service, Quality Metrics, NIfTI-1, Epilepsy, Stroke, Alzheimer Disease, Diabetes Mellitus, Dyslexia, Hypertension, Parkinson Disease, Multiple Sclerosis,
