This project aims to perform assessment of corneal ulcer progression using digital image processing. Corneal ulcer isa type of eye disease that presently approaches 1.5 to 2 millions patients per year at developing world, estimated by World Health Organization. Current methods are mainly clinical assessment and bacteriological identification. Several problems are identified, which are parameters measured are inaccurate, difficulties in handling patients and only same ophthalmologist has to examine the progression of a patient. The study focuses onenhances and analyze eye images. Several steps of image enhancement have been performed by MATLAB to increase quality of the images. The methods used are grayscale conversion, intensity vale adjustment, image subtraction and thresholding. Analysis of corneal ulcer progression is established by using parameters measured; area, height and width. Finally, graphical user interface (GUI) is developed. Its aim is to ease ophthalmologist in monitoring corneal ulcer progression.
