Enhancement of Retinal Image by Hybrid Approach

Abstract

Diabetic retinopathy (DR) has been perceived as root cause of blindness among all age groups. DR if not detected at early stage can be proved fatal. So, the early detection of DR is must. The foundation of this research paper is to enhance the retinal images which can furtherance in early detection of the disease. The enhancement methodology is framed by hybrid use of Gabor filter, median filter, and mean filter. This hybrid approach is accomplished with altered mathematical equations. The detailed working of the adopted methods have been deeply explained in the research paper with algorithms. The PSNR, MSE, and RMSE values of proposed technique have been calculated and compared with existing methods like CLAHE and Morphological Operations.
