Statistical analysis of the parameters of the optic disk image

In recent time much attention is payed to the computer analysis of the optic disc (OD) images, aimed at extracting the objective statistical characteristics of the OD image. In the present paper we describe a computer program that allows the determination of the mean colour indices, their variance, etc., for different regions of the OD. The total colour space in the RGB model is divided into subdomains in correspondence with the values of the mask that determines the subdomain boundaries. A simple method of determining the domain of the OD physiological excavation by the value of the variability coefficient is proposed.
