Abstract

The simultaneous calculation of projections in two orthogonal directions during a row by row scanning of an image is explained. A description is given of a method which allows the calculation of projections 'which have arbitrary angles with the pixel grid directions. The use of fifo's, interleaved and conditional carry processing to optimize this calculation is discussed. These techniques make a compact implementation possible with a high processing speed.
