For such a stereokinetic visual function, numerous recovery methods have been proposed for 3\u2010D information from 2\u2010D images. However, past methods of recovery have a problem in that the accurate recovery is impossible unless the image data have a high accuracy. For example, the input data must have the accuracy of 10 decimal digits. On the other hand, the human seems to perceive the 3\u2010D structure of the object from the data with a relatively low accuracy by another means, such as a long\u2010term observation.<\/jats:p><jats:p>This paper discusses a method of recovery where the 3\u2010D structure is recognized with as high an accuracy as possible from the data with a relatively low accuracy using a number of frames. Rigid bodies connected by joints are considered as the objects. When the information concerning the positions and velocities of several points on the object projected on a plane are provided, the depth information is recovered. By a computer simulation, it is seen that if approximately 10 or more frames are available, the output result with one order of magnitude lower accuracy than that of the input data can be obtained.<\/jats:p>","DOI":"10.1002\/scj.4690220705","type":"journal-article","created":{"date-parts":[[2007,7,7]],"date-time":"2007-07-07T21:16:38Z","timestamp":1183842998000},"page":"41-50","source":"Crossref","is-referenced-by-count":0,"title":["A method for recovery of the 3\u2010d structure and motion of objects from low\u2010accuracy dynamic images"],"prefix":"10.1002","volume":"22","author":[{"given":"Kazuhisa","family":"Takagi","sequence":"first","affiliation":[]},{"given":"Noboru","family":"Ohnishi","sequence":"additional","affiliation":[]},{"given":"Noboru","family":"Sugie","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2007,3,22]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.7551\/mitpress\/3877.001.0001"},{"key":"e_1_2_1_3_2","unstructured":"K.TasakiandT.Oyama.Visual Information Processing(1979)."},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0734-189X(84)90034-3"},{"key":"e_1_2_1_5_2","first-page":"76","volume-title":"Visual Motion Perception","author":"Johansson G.","year":"1976"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/C-M.1981.220561"},{"key":"e_1_2_1_7_2","doi-asserted-by":"crossref","first-page":"195","DOI":"10.1007\/BF00340076","article-title":"The interpretation of biological motion","volume":"42","author":"Hoffman D.
