A complex computation is required to transform the orthogonal coordinates into the polar coordinates. In this paper, a transformation algorithm is proposed using DDA, which is a high\u2010speed algorithm to generate the digital segment. To evaluate the usefulness of the proposed algorithm, a computer experiment was performed using several input images from a TV camera. The mean error of the rotational angle was \u00b10.8 deg, and the maximum error was \u00b13.9 deg, which is quite satisfactory.<\/jats:p>","DOI":"10.1002\/scj.4690180305","type":"journal-article","created":{"date-parts":[[2007,7,7]],"date-time":"2007-07-07T13:33:30Z","timestamp":1183815210000},"page":"40-51","source":"Crossref","is-referenced-by-count":0,"title":["Transformation of orthogonal coordinates into polar coordinates using DDA\u2010computation of the angle of rotation of an object"],"prefix":"10.1002","volume":"18","author":[{"given":"Masayuki","family":"Ueno","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiromitsu","family":"Hama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazumi","family":"Yamashita","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":"289","volume-title":"Lectures in Applied Mathematics","author":"Ikehara S.","year":"1966"},{"issue":"8","key":"e_1_2_1_3_2","first-page":"981","article-title":"Transformation\u2010invariant Fourier spectrum and normalization of patterns","volume":"65","author":"Hama H.","year":"1982","journal-title":"Trans.
