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.

A method of personal identification includes switching between visible and near infrared light, acquiring palmprint image and palm vein image from a person under the visible and the near infrared light, extracting sub-images from the palmprint image and the palm vein image based on a region of interest, extracting multiple features from the sub-images, and matching the extracted multiple features with stored information in a database to authenticate the person.
