Abstract

An image processing system based on a MC 68000 microprocessor has been developed for analysis of fundus photographs. This personal computer based system has specific image enhancement capabilities comparable to existing large scale systems. Basic enhancement of fundus images consists of histogram modification or kernel convolution techniques to determine regions of specific interest such as textural difference in the nerve fiber layer or cupping of the optic nerve head. Fast Fourier transforms and filtering techniques are then utilized for specific regions of the original image. Textural difference in the nerve fiber layers are further highlighted using either interactive histogram modification or pseudocolor mappings. Menu driven software allows review of the steps applied, creating a feedback mechanism for optimum display of the fundus image. A wider noise margin than that of digitized fundus photographs can be obtained by direct fundus imaging. The present fundus image processing system clearly provides us with quantitative and detailed techniques of assessing textural changes in the fundus photographs of glaucoma patients and suspects for better classification and early detection of glaucoma. The versatility and computing capability of the system make it also suitable for other applications such as multidimensional image processing and image analysis.
