This paper proposes a new algorithm for extracting the representative 2\u2010D projected shape. In this method, a viewing area showing the same appearance is drawn and expressed on a viewing vector map that is the orthogonal coordinate graph expressed by the deflection angle (\u03b1, \u03b2) of a viewing vector in a polar coordinate system. A viewing vector map is divided into the viewing regions showing the same appearance by drawing the visible region of each surface and the boundary line showing the occlusion between surfaces.<\/jats:p><jats:p>The representative 2\u2010D projected shapes for the 3\u2010D object are obtained by extracting the representative points in each divided region on a viewing vector map. The representative projected shape for a stable postrue of the 3\u2010D object is extracted easily by drawing the trace of the viewing point based on a stable posture of the object and the position of the TV camera on a viewing vector map. Furthermore, the approximate ratio of each viewing region showing the same appearance to the 3\u2010D view space can be calculated easily. This ratio shows the appearance probability.<\/jats:p>","DOI":"10.1002\/scj.4690240404","type":"journal-article","created":{"date-parts":[[2007,7,8]],"date-time":"2007-07-08T00:43:55Z","timestamp":1183855435000},"page":"34-45","source":"Crossref","is-referenced-by-count":1,"title":["Automatic extraction of the representative 2\u2010D projected shape for polyhedral object from viewing vector map"],"prefix":"10.1002","volume":"24","author":[{"given":"Kozo","family":"Fujimoto","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masato","family":"Kimoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuji","family":"Nakata","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,3,21]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"192","volume-title":"Property Spheres: A New Representation for 3\u2010D Recognition","author":"Feket G.","year":"1984"},{"key":"e_1_2_1_3_2","first-page":"458","volume-title":"The 3\u2010D Profile Method for Object Recognition","author":"Hebert M.","year":"1985"},{"issue":"1","key":"e_1_2_1_4_2","first-page":"127","article-title":"Determining object attitude and position for bin\u2010picking tasks guided by an interpretation tree derived from a geometrical modeler, Jour","volume":"70","author":"Ikeuchi K.","year":"1987","journal-title":"I.E.I.C.E."},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.7210\/jrsj.6.271"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00337644"},{"key":"e_1_2_1_7_2","first-page":"336","volume-title":"Characteristic Views as a Basis for Three\u2010Dimensional Object Recognition","author":"Chakravaty I.","year":"1982"},{"key":"e_1_2_1_8_2","first-page":"494","volume-title":"Creating the Perspective Projection Aspect Graphof Polyhedral Objects","author":"Stewman J.","year":"1988"},{"key":"e_1_2_1_9_2","first-page":"123","volume-title":"Aspect Graphs for Convex Planar\u2010Face Objects","author":"Stewman J.","year":"1987"},{"key":"e_1_2_1_10_2","first-page":"240","volume-title":"A Model for Describing Surface Shape","author":"Callahan J.","year":"1985"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1109\/34.44399"},{"key":"e_1_2_1_12_2","first-page":"30","volume-title":"Efficiently Commputing the Aspect Graph of Polyhedral Objects","author":"Gigus Z.","year":"1988"},{"issue":"11","key":"e_1_2_1_13_2","first-page":"662","article-title":"Topological properties in digitized binary pictures, Jour","volume":"56","author":"Yokoi S.","year":"1973","journal-title":"I.E.C.E"}],"container-title":["Systems and Computers in Japan"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fscj.4690240404","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/scj.4690240404","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,25]],"date-time":"2023-10-25T21:36:37Z","timestamp":1698269797000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/scj.4690240404"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1993,1]]},"references-count":12,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1993,1]]}},"alternative-id":["10.1002\/scj.4690240404"],"URL":"https:\/\/doi.org\/10.1002\/scj.4690240404","archive":["Portico"],"relation":{},"ISSN":["0882-1666","1520-684X"],"issn-type":[{"value":"0882-1666","type":"print"},{"value":"1520-684X","type":"electronic"}],"subject":[],"published":{"date-parts":[[1993,1]]}}}
