The target to pursue is a dark spot on colonoscopic images, called “pattern”. A novel methodology for \"pattern\" extraction and tracking was designed. Surgeons observations leads to the basic idea of this technique. Information about target position is then continues and makes possible prediction of the “pattern” position. A set of endoscopic images is tested to demonstrate the effectiveness of the vision technique. An experiment tool to simulate the endoscope navigation was employed to achieve real time performance. An interpretation of the results and the possible amelioration is presented.","license":"You are licensing your work to Kitware Inc. under the\nCreative Commons Attribution License Version 3.0.\n\nKitware Inc. agrees to the following:\n\nKitware is free\n * to copy, distribute, display, and perform the work\n * to make derivative works\n * to make commercial use of the work\n\nUnder the following conditions:\n\\\"by Attribution\\\" - Kitware must attribute the work in the manner specified by the author or licensor.\n\n * For any reuse or distribution, they must make clear to others the license terms of this work.\n * Any of these conditions can be waived if they get permission from the copyright holder.\n\nYour fair use and other rights are in no way affected by the above.\n\nThis is a human-readable summary of the Legal Code (the full license) available at\nhttp://creativecommons.org/licenses/by/3.0/legalcode","keywords":["Surgical Robotic, Colonoscopy, Minimally Invasive Surgery, Medical Imaging, Visual control."],"authors":[{"name":"Chettaoui, Hanene","email":"hchettaoui@yahoo.fr","affiliations":["LAI INSA Lyon "],"corresponding":true},{"name":"Thomann, Guillaume","affiliations":[]},{"name":"Ben Amar, Chokri","email":"chokri.benamar@ieee.org","affiliations":[]},{"name":"Redarce, Tanneguy","affiliations":[]}],"date_submitted":"2006-06-30T16:51:03Z","external_publication_id":105,"revision_cids":["bafkreibbtrgcrz3sjr5blxm5vig5z5mshikdibnsfbt5hfu6ehouhdadby"]},"mdast":{"type":"root"},"downloads":[{"url":"https://ipfs.desci.com/ipfs/bafkreibeycmiraumdlzm7f7it2gsujaqjj5oewwbq7fuvafmvkbkwbig6e","title":"root/insight-journal-metadata.json","filename":"insight-journal-metadata.json","extra":{"size_bytes":9233,"type":"file"}},{"url":"https://ipfs.desci.com/ipfs/bafkreidrip726iw3jbwoxfx2ngjedums5z46mybgpj5r5sgwlx7yiegfle","title":"root/reviews.md","filename":"reviews.md","extra":{"size_bytes":5455,"type":"file"}}],"references":{"cite":{"order":[]},"data":{}}}
