Abstract:

In this article we discuss the first approach to analysing so called drop pictures using computer methods. A transformation of the pictures on Fourier-Bessel spectra was implemented with the aid of original programs. These spectra are compared using standard statistical methods. Gradual back transformation of the pictures allows for detection of details that have distinct spectral characteristics.
