Segmentation Of Retina -Based On Fractional Pso Technique

Abstract: Glaucoma is the third leading cause of blindness, characterized by gradual damage to the optic nerve and result in visual field loss. Particle Swam Optimization Algorithm is a recent meta heuristic that has been inspired from social behavior of fishes, bees, birds, etc, that live together in colonies. In this frame work, the segmentation process is constrained by two prior models; a shape prior model and a texture prior model. Furthermore, the particle swarm optimization algorithm is used to refine the preliminary segmentation according to the shape prior model. In this work, we tested the proposed technique for the segmentation scans and the obtained results show the efficiency of the proposed technique to accurately delineate the desired objects.
