Abstract

This paper proposes an automated method for detecting microcrystal structure distortions on a tear crystallogram using the Karhunen-Loeve expansion (KLE) with preliminary construction of the crystallogram directions' field. The method implies optical implementation: we propose a scheme for optically constructing the image directions' field using a rotating slot. Using the ophthalmologist selected samples of crystallograms a computer-aided simulation has been conducted.
