Abstract : This paper deals with a recognition system specialized for low pixel numbers. It is assumed that the image consists of 15 x 15 pixels. Using such a low pixel number, the object is distorted beyond recognition if its straight edges are not lined up with the grid. This is especially important if the previously described method based on interpretation of each pixel row as a binary number is used. Therefore, it is shown that a given image of a randomly oriented object can be rotated by a subroutine requiring only little processing time. The resultant image deviates only to a minute degree from the image which would have been observed with its straight edges lined up with the pixel grid. Originator-supplied key words included: Low Pixel Numbers, Pattern Recognition, Multiaperture Optics, Recognition Coefficient.
