Processing a Class of Ophthalmological Images Using an Anisotropic Diffusion Equation
Andrew P. Papliński, James F Boyce · 1999
In this paper we discuss application of an anisotropic diffusion equation in processing Posterior Capsular Opacification (PCO) Images. Such images are recorded to monitor the state of a patient's vision after cataract surgery. Non-linear filtering using an anisotropic diffusion equation generates segmentation-like results by enhancing edges represented by the high value of the gradient and smoothing away small inter-regional features. The algorithm ensures an existence of a stable fixed-point solution and maintains a mean grey level of image intensity. Keywords: Medical Imaging, Posterior Capsular Opacification, Partial Differential Equations, Anisotropic Diffusion Equation, Segmentation. This is to certify that if the paper is accepted one of the authors will attend the conference to present it. Address for correspondence: Dr Andrew P.
