We present a new system for segmentation of MR images of the brain, based on a novel modification of the watershed transform. Our proposed improvement is to substitute the single contour detection function (usually the gradient) of the original watershed transform with a set of functions especially tailored for the detection of each structure in the image. In this paper, these functions are based on a previous probability calculation, using normal distributions and a Markov Random Field. To improve the detection of the sulci, where the partial volume effect often masks the presence of CSF, the probability values for gray matter and CSF are modified using the absolute value of the distance to the white matter and the ridgeness of this distance. We also propose a novel way to initialize the watershed transform by using a probabilistic atlas: in this way, no user interaction is needed. Validation experiments indicate an accurate segmentation of the interesting structures. 2020 true true true true false NONE 2024-06-05 false 0 0 0 0 0 0 0 0 0 0 0 0 1 1 false false false false 2023-04-17T13:55:29.647+0000 1 7 0 4 0 true true 10002 English /api/language/10002 Angol Language true 2 false true 10939 true 10017 /api/country/10017 Country true 13 /api/city/10939 City true 2054246 true 651479 /api/publicationidentifier/651479 https://www.worldcat.org/search?q=isbn%3A0780377893 0780377893 PublicationIdentifier true 122 ISBN https://www.worldcat.org/search?q=isbn%3A@@@ /api/publicationsource/122 ISBN PlainSource true true 10002 /api/publicationsourcetype/10002 PublicationSourceType true false 122 true false true 16544423 /api/publicationidentifier/16544423 https://www.worldcat.org/search?q=isbn%3A9780780377899 9780780377899 PublicationIdentifier true 122 ISBN https://www.worldcat.org/search?q=isbn%3A@@@ /api/publicationsource/122 ISBN PlainSource true true 10002 /api/publicationsourcetype/10002 PublicationSourceType true false 122 true true /api/publication/2248899 true true 23 23 /api/publicationtype/23 PublicationType 3 true 23 Book PROCEEDINGS OF THE 25TH ANNUAL INTERNATIONAL CONFERENCE OF THE IEEE ENGINEERING IN MEDICINE AND BIOLOGY SOCIETY, VOLS 1-4 2248899 false 2248899 true true true true true 10000144 Conference proceedings true 23 23 /api/publicationtype/23 PublicationType 3 true 23 Book /api/subtype/10000144 Konferenciakötet SubType 345 true 10000144 false Book 2003 true 1 /api/category/1 Category true 1 false Language 10002 /api/language/10002 Angol English true 2 true PersonAuthorship 93148434 /api/authorship/93148434 1 0.0 true false true Grau V true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 93148435 /api/authorship/93148435 2 0.0 false false false Kikinis R true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 93148436 /api/authorship/93148436 3 0.0 false false false Alcaniz M true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 93148437 /api/authorship/93148437 4 0.0 false true false Warfield SK true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PublicationIdentifier 17535672 /api/publicationidentifier/17535672 PlainSource 6 /api/publicationsource/6 PublicationSourceType 10001 /api/publicationsourcetype/10001 true true true DOI DOI https://doi.org/@@@ true true 6 true 10.1109/IEMBS.2003.1279828 https://doi.org/10.1109/IEMBS.2003.1279828 false true PublicationIdentifier 17535671 /api/publicationidentifier/17535671 PlainSource 1 /api/publicationsource/1 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true WoS WoS https://www.webofscience.com/wos/woscc/full-record/@@@ true true 1 true 000189395300164 https://www.webofscience.com/wos/woscc/full-record/000189395300164 false true /api/publication/31530453 <div class="BookChapter Publication long-list"> <div class="authors"> <img title="Idézőközlemény" style="float: left" src="/frontend/resources/grid/publication-citation-icon.png"> <div class="autype autype0"> <span class="author-name" >Grau V ✉ </span> ;&nbsp;&nbsp;&nbsp;
