Even though much effort has been invested in surface description, robust extraction of surface parameters from scattered and noisy 3-D measurements is still a delicate task. For a given visible surface section, the extracted parameters should not depend on the sensor position in the scene nor on a particular measurement set on this surface. In this work, we show that a viewpoint invariant and stable local surface description can be extracted on sections where measurement constraints are redundant with respect to a polynomial model. A segmentation approach is developed to identify such stable sections. The approach is based on a measurement error model which takes into account the sensor\u2019s viewpoint. An application of the approach to the extraction of straight line sections from single scan 3-D surface profiles is presented. The extracted stable linear sections are stored in a list that includes the estimated descriptive parameters for each section and indices of reliability for each description. The descriptive parameters obtained from images of the objects is compared with pre-measured parameters. <\/jats:p>","DOI":"10.1142\/s0218001494000668","type":"journal-article","created":{"date-parts":[[2004,11,19]],"date-time":"2004-11-19T02:21:13Z","timestamp":1100830873000},"page":"1319-1342","source":"Crossref","is-referenced-by-count":1,"title":["FROM 3-D SCATTERED DATA TO GEOMETRIC SIGNAL DESCRIPTION: INVARIANT STABLE RECOVERY OF STRAIGHT LINE SEGMENTS"],"prefix":"10.1142","volume":"08","author":[{"given":"PATRICK","family":"H\u00c9BERT","sequence":"first","affiliation":[{"name":"Laboratoire de Vision et Syst\u00e8mes Num\u00e9riques, D\u00e9partement de G\u00e9nie \u00c9lectrique, Universit\u00e9 Laval, Qu\u00e9bec, Canada, G1K 7P4, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"DENIS","family":"LAURENDEAU","sequence":"additional","affiliation":[{"name":"Laboratoire de Vision et Syst\u00e8mes Num\u00e9riques, D\u00e9partement de G\u00e9nie \u00c9lectrique, Universit\u00e9 Laval, Qu\u00e9bec, Canada, G1K 7P4, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ROBERT","family":"BERGEVIN","sequence":"additional","affiliation":[{"name":"Laboratoire de Vision et Syst\u00e8mes Num\u00e9riques, D\u00e9partement de G\u00e9nie \u00c9lectrique, Universit\u00e9 Laval, Qu\u00e9bec, Canada, G1K 7P4, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"container-title":["International Journal of Pattern Recognition and Artificial Intelligence"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218001494000668","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,7]],"date-time":"2019-08-07T02:12:41Z","timestamp":1565143961000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0218001494000668"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1994,12]]},"references-count":0,"journal-issue":{"issue":"06","published-online":{"date-parts":[[2011,11,21]]},"published-print":{"date-parts":[[1994,12]]}},"alternative-id":["10.1142\/S0218001494000668"],"URL":"https:\/\/doi.org\/10.1142\/s0218001494000668","relation":{},"ISSN":["0218-0014","1793-6381"],"issn-type":[{"value":"0218-0014","type":"print"},{"value":"1793-6381","type":"electronic"}],"subject":[],"published":{"date-parts":[[1994,12]]}}}
