Implementation of image enhancement techniques for vein patterns in eye

Biomedical Image Processing is one of the significant DSP applications which need accurate mathematical platform to produce best results in understanding and to diagnose the various diseases. Eye is one of the sensitive organs in human body which have disorders like Glaucoma, Diabetic and Hypertensive Retinopathy, Retinal Vascular Occlusion etc., are not visible to naked eye; hence images of eye's back part are captured using fundus photography are processed. Various applications like Image Negative, Image Enhancement, Image Segmentation and Image Contrast Stretching are modeled in MATLAB using Simulink and Xilinx blocksets and the code is generated using Xilinx System Generator (XSG) Token. Power calculations, Timing and Delay calculations, Look Up Table (LUT) calculations are performed to implement design on FPGA. The results obtained from Power calculations and Delay calculations shows that techniques developed here consumes relatively low power and combinational path delay is less.
