چکیده
There are many systemic diseases that affect the functioning and working of the eye. Some of the major parts of the eye like iris, retina, and optic nerve are affected due to systemic diseases like diabetes, AIDS, glaucoma, hypertension, macular degeneration, swelling in the brain and many more. Glaucoma is the condition of eye caused by increase in intraocular pressure. Early detection of this can help prevent complete vision loss. In this paper, the optic disc, optic cup and neuroretinal rim regions were extracted from the retinal fundus images using unsharp filter, morphological as well as logical operations. Their corresponding features like cup-to-disc ratio (CDR) and neuroretinal rim (NRR) ratio were found, based on which, the fundus images were classified as glaucomatous or normal patients.

A Parallel multiplier using approximate compressors are proposed in this paper. The two new approximate 4-2 compressors are proposes that the simplified compressors have better power consumption than the optimized 4-2 compressor existing designs. These approximate compressors are then used in the restoration module of a Parallel multiplier. Four different schemes for utilizing the proposed appr...

several edge recognition strategies have now been planned within the past decades. Many are derived from differential strategies such as for example Sobel, Roberts, Laplacian operators, and therefore on. Nevertheless these calculations are quite sensitive to sound, in order to restrain sound before sensing edges. In this report intensive literature review has been presented in numerous edge rec...

This paper describes the cross-talk analysis of high-speed PCB design. Some models using multiple PCB traces above a ground plane having guard traces and vias are taken and the results are obtained from modeling and simulation using Ansoft HFSS software tool and are compared with the experimental results. Reduction techniques of crosstalk are highlighted.

Input vector monitoring concurrent built-in selftest schemes perform testing during the normal operation of the circuit without imposing a need to set the circuit offline to perform the test. These schemes are evaluated based on the hardware overhead and the concurrent test latency i.e., the time required for the test to complete, whereas the circuit operates normally. In this brief, we present...
