Paper Abstract

Image recognition methods based on evaluation of intensity Fourier-spectrum circular and radial harmonics are attractive for applications due to the possibility to obtain a range of features invariant to the shift, rotation and change scale of the input image. Application of array of photodetectors with special topology in a combination with digital postprocessing allows to achieve high accuracy of measurement of harmonics in optics. In paper results of experiments of high accuracy measurement of circular and radial harmonics are presented.
