This method rotates images by combining two skew transformations of raster scanning along <jats:italic>X<\/jats:italic> and <jats:italic>Y<\/jats:italic> axes. It makes possible group access to horizontally or vertically adjacent pixels in the memory, and shortens memory read\/write time per pixel. Each skew transformation includes scale change of images in which the scale factor is approximated by a rational number. The resultant periodicity in transformation is used for high\u2010speed processing by simple table look\u2010up operation. The estimated rotation time of images is 250 \u2010 375 ns per pixel with a two\u2010dimensional memory of transfer speed 1 m\u0308s\/word (1 word = 16 bits) and the pixel shift clock time 125 ns (8 MHz). The scaling error due to rational number approximation depends on the transformation table capacity. The table capacity being 32 or 16 digits, the error is approximately 0.3 or 0.8 percent, respectively. In applying to document image editing, the table of 16 to 32 digits is practically sufficient, implemented by a small number of IC's (about 100). The effectiveness of this method is justified with those examples.<\/jats:p>","DOI":"10.1002\/scj.4690171108","type":"journal-article","created":{"date-parts":[[2007,7,7]],"date-time":"2007-07-07T10:51:43Z","timestamp":1183805503000},"page":"76-87","source":"Crossref","is-referenced-by-count":0,"title":["High\u2010speed rotation of digital images by raster scanning and table\u2010lookup operations"],"prefix":"10.1002","volume":"17","author":[{"given":"Kuniaki","family":"Tabata","sequence":"first","affiliation":[]},{"given":"Haruo","family":"Takeda","sequence":"additional","affiliation":[]},{"given":"Tetsuo","family":"Machida","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2007,3,21]]},"reference":[{"key":"e_1_2_1_2_2","unstructured":"Muraoka SuganoandTakagi.
