Apparatus and method for non-invasive diabetic retinopathy detection and monitoring

摘要

A fundus camera using infrared light sources, which included an imaging optical path and an optical path for focusing and positioning and two optical paths share a common set of retina objective lens, and a computer-assisted method for retinal vessel segmentation in general and diabetic retinopathy (DR) image segmentation in particular. The method is primarily based on Multiscale Production of the Matched Filter (MPMF) scheme, which together the fundus camera, is useful for non-invasive diabetic retinopathy detection and monitoring.

主权项

1. A method of segmentation of a color retinal image for Diabetic Retinopathy (DR) diagnosis, the method comprising the steps of:
(a) erasing edges of bright objects from a color retinal image by nearest neighbor interpolating, whereby an interpolated image is generated; (b) extracting vessel candidates from the interpolated image using multiscale production of matched filter; (c) eliminating non-vessels based on vessel texture feature measurement; (d) erasing edges of bright objects from the color retinal image by fast digit inpainting whereby an inpainted image is generated; and (e) extracting an optic disk from the inpainted image; wherein the vessel texture feature measurement comprises applying spatial-statistical measurement for feature presentation.
