ABSTRACT
High rated and active research in Ophthalmic field has paved the way for the detection of several retinal disorders which helps the ophthalmologist, in scheduling and executing timely treatment. There exist different imaging device for retinal examination in ophthalmology with varying degrees of resolution. The images obtained from such imaging devices contains noise which must be eliminated for producing accurate results. This paper mainly concentrates on using boosted anisotropic diffusion filter (BADF) which outperforms the existing anisotropic diffusion filter and is compared with different filters to authenticate the performance. Various performance measures are taken into considerations which are mean square error, structural similarity index, peak signal to noise ratio and signal to noise ratio. The proposed work is tested for 20 images (10 abnormal BRAO from clinical database and 10 normal images). This paper clearly concludes that BADF helps the radiologist in accurate retinal examination and thereby reducing the risk factors.
