Abstract

An area distribution of Corneal Endothelial Cell(CEC) include important clinical information. In this paper, we present a two-step processing method of contour complement for the CEC. In the first step; we apply not only conventional Laplasian Gaussian filters(LGF) but also three-arrow-shaped LGFs which is newly developed to extract vertices of hexagonal shapes. In the second step; we complement the lacking part of CEC by using an energy minimum algorithm. Using the results, we measure areas of CEC.
