{"year":"2010","abstract":[{"text":"In cortex surface segmentation, the extracted surface is required to have a particular topology, namely, a two-sphere. We present a new method for removing topology noise of a curve or surface within the level set framework, and thus produce a cortical surface with correct topology. We define a new energy term which quantifies topology noise. We then show how to minimize this term by computing its functional derivative with respect to the level set function. This method differs from existing methods in that it is inherently continuous and not digital; and in the way that our energy directly relates to the topology of the underlying curve or surface, versus existing knot-based measures which are related in a more indirect fashion. The proposed flow is validated empirically.","lang":"eng"}],"title":"Topology noise removal for curve  and surface evolution","_id":"3782","alternative_title":["LNCS"],"month":"12","date_published":"2010-12-31T00:00:00Z","oa_version":"None","conference":{"location":"Beijing, China","end_date":"2010-09-20","name":"MCV: Medical Computer Vision","start_date":"2010-09-20"},"date_updated":"2021-01-12T07:52:10Z","doi":"10.1007/978-3-642-18421-5_4","author":[{"first_name":"Chao","id":"3E92416E-F248-11E8-B48F-1D18A9856A87","full_name":"Chen, Chao","last_name":"Chen"},{"last_name":"Freedman","full_name":"Freedman, Daniel","first_name":"Daniel"}],"date_created":"2018-12-11T12:05:08Z","status":"public","type":"conference","quality_controlled":"1","department":[{"_id":"HeEd"}],"publication":" Conference proceedings MCV 2010","acknowledgement":"Partially supported by the Austri an Science Fund unde r grant P20134-N13.\r\nWe thank Helena Molina-Abril for very helpful discussion.
