title: Enhancement of fundus photographs taken through cataracts.
abstract: Image-enhancement techniques can aid the clinician in evaluating fundus pictures taken through cataracts. The degradation of the fundus image by cataracts has been described as low-pass filtering. Means to partially overcome this degradation using homomorphic filtering and adaptive enhancement are presented. The clinical value of these enhancement techniques is demonstrated with two cases of progressive glaucoma and cataracts.
