Paper Abstract
The work described was originally aimed at providing a new diagnostic technique for the early detection of malignant ocular tumors through their spectral signature. The instrument developed comprises a modified fundus camera, a Charge-coupled device (CCD) camera and a 16 bit microcomputer equipped with floppy disk drives and a 512 x 512X 8-bit display device. The system allows the recording of digitized fundus or iris reflectance pictures in eight spec-tral bands between 500 and 1100 nm. After calibration and preprocessing of the data, a multi-spectral analysis is performed by means of a VAX computer. The image processing methods are described and their ability to characterize pigmented lesions or other ocular anatomical fea-tures through their spectral signature is evaluated.
