METHOD AND DEVICE FOR IMAGE DETECTION Russian patent published in 2000 - IPC

FIELD: computer engineering. SUBSTANCE: method uses matrix of detectors which is produced after passing light beams through encoding mask, which consists of holes and jumpers and encoded by random numbers. Goal of invention is achieved by comparison of number of ones and zeros in matrix of detectors from arbitrary point in space using mask encoded by random numbers or such mask in which jumpers are replaced by holes and holes to jumpers so that identical number of ones and zeros corresponds to absence of beam in particular point, while different number of ones and zeros corresponds to presence of beam. EFFECT: increased speed, possibility of image detection for continuously moving object. 2 cl, 3 dwg
