Diabetic retinopathy - microaneurysm early diagnosis and prognosis assessment
Journal Title: MedPulse -International Medical Journal - Year 2016, Vol 3, Issue 8
Abstract
Objective: To detect microaneurysms in retinal fundus images involving the selection of green channel of retinal fundus image illumination smoothing of retinal fundus image by bi-cubical interpolation blood vessel detection. Materials and Methods: Prospective randomised study retinal fundus images of 25 diabetic patients subjected to Rotational cross-sectional profile analysis on the regional maximum pixels and the peak properties are measured. The statistical parameters like mean standard deviation, co-efficient of variation of feature set are calculated. The microaneurysm candidates are estimated by comparison of distribution from the values of mean and standard deviation with the training set obtained from various datasets. Applications: The final MA candidates obtained can be used to diagnose developments in the earlier stages of diabetic retinopathy.
