| Abstract;The right angle rotation of an image is one of the fundamental functions in image processing and is applied to document image processing in the office. This method can execute a high-speed rotation of binary image based on coordinate data for the start and the end of the run, which is suited to the general-purpose processor. The rotation method is based on the transformation of run data in the vertical and horizontal directions. A document image is actually rotated by right angle on a conputer. The processing time was examined to demonstrate experimentally the usefulness of the proposed method. (author abst.) |
