Image Preprocessing and Analysis on Eye Fundus Images Segmentation by Using Density Clustering Methods
Abstract: In order to do an automated evaluation of various retinal illnesses such as Diabetic retinopathy, Glaucoma, and Macular Edema, fundus images must be pre-processed first. For many reasons, it's difficult to accurately detect the optic disc. Many blood vessels cross the optic disc, making it difficult to discern the disc's boundaries in fundus images. Lesion regions in diabetic retinopathy look very much like an optic disc's colour and texture, so …

Application of Sensor Effect on Chlorodiazepam of Polyaniline Doped Silver Nanocomposite
Abstract: In order to ease the creation of the polymeric nanocomposite known as PANI/Ag, pani-doped silver nanoparticles were oxidised chemically and then exposed to the oxidation process. Aniline with varying amounts of silver nanoparticles added to it can be used to make a nanocomposite known as PANI/Ag in an acid solution at room temperature by employing ammonium persulfate as the oxidising agent. This can be done by using aniline with different …
