Abnormalities in the vascular structure of a retina, such as abnormal changes in thickness of vessel, tortuosity, or the appearance of retinal lesions, may be associated with the occurrence of retinopathy diseases. An automated structural analysis of changes in vessel morphology may help indicating the clinical signs of retinopathies, describing their early occurrence or severity. We propose a framework...
This paper presents a hard clustering technique using fireworks algorithm with adaptive transfer function (FWAATF) for image segmentation. The fireworks algorithm (FWA) is a recently developed new Swarm Intelligence (SI) algorithm for function optimization. This algorithm simulates the process of fireworks explosion in the night sky. The main characteristic of FWA is the good balance between exploration...
Image based applications such as target tracking, tumor detection, texture extraction requires an efficient image segmentation process. The partitioning of image into various non- overlapping distinct regions refers the image segmentation. Various segmentation techniques like edge, threshold, region, clustering and neural network are involved in the effective image analysis. The efficiency of the...
