Bones form the supporting framework of the body. It has a hard outer layer made of compact (cortical) bone that covers a lighter spongy (trabecular) bone inside. Osteoblast (cell that lays down new bone) and osteoclast (cell that dissolves old bone) are the two types of cells present in the bone. Throughout our lifetime, new bone keeps replacing the dissolving old bone. An uncontrollable division...
This Paper presents an object tracking system based on FPGA using canny edge detection Algorithm. The system consists of canny edge detection algorithm implemented on FPGA kit to identify edges of real time object. Also a tracking and reorganization of object is done by Smartphone camera. Canny edge detection algorithm is key stage in image processing and object recognizing application. The field...
Skull stripping is an important image processing step in many neuroimaging studies. In this paper, a novel scheme based on a level sets representation of the geodesic active contour (GAC) is employed to detect the boundary of the skull. This approach is based on the relation between active contours and the computation of geodesics (minimal length curves). The contour is evolved from inside the MR...
Increased need of the automatic authentication of persons has led to extensive researches in biometrics. Among all biometrics, iris recognition is one of the most promising methods due to rich and unique textures of the iris, noninvasiveness, stability of iris pattern throughout the human life time, public acceptance, and availability of user friendly capturing devices. Iris segmentation is the vital...
Liveness detection is an important and challenging issue in iris recognition system security against spoofing. In this paper, a new iris liveness detection method is proposed against semi-transparent contact lens based spoofing. The proposed method works through iris texture dissimilarity between two iris regions due to pupillary light reflex. The texture dissimilarity is computed in the iris region...
