Reliable detection of irises is a necessary precondition for any iris-based biometric identification system. It is also important in measuring the movement of eyes in applications such as alertness detection and eye-guided user interfaces. This paper introduces a novel iterative algorithm for the accurate and fast localization of irises in eye images.

Radiologically guided localization procedures are indicated pre-operatively when breast lesions are nonpalpable. The results of 42 percutaneous hookwire localizations over a period of 3 years are described. Of the total, 7 (17%) were found to be malignant. Biopsy was indicated by mammographically detected mass in 48%, by microcalcifications in 40% and by microcalcifications with an associated m...

Foreign bodies lodged in the intraconal space of the orbit pose a surgical challenge due to its deep location behind the globe. Image-guided endoscopic transnasal surgery facilitates the localization of the metallic foreign bodies and enables its safe removal with minimal surrounding tissue damage and optic nerve injury.

Cloud computing used for task scheduling which guided by broker and computer by virtual machine, but cost of computation will increase if use random task localization and this problem exponential high when use workflow which have huge number of task with dependency, so in this paper optimize the cost and time by intelligent and colony optimization which give decision to broker.

This paper presents an approach to 6-DOF simultaneous localization and mapping (SLAM) particularly suited for collision avoidance in visually guided robotic manipulation tasks in dynamic or unknown environments. We exploit the properties of novel RGB-D sensors such as the Microsoft Kinect to build highly accurate voxel maps.

objectives: the aim of the present study was to assess the auditory lateralization ability in children with (central) auditory processing disorder. methods: participants were divided in two groups: 15 children with central auditory processing disorder (8-10 years) and 80 normal children (8-11 years) from both genders with pure-tone air-conduction thresholds better than 20 db hl bilaterally and ...

a wireless sensor network (wsn) is a wireless decentralized structure network consists of many nodes. nodes can be fixed or mobile. wsn applications typically observe some physical phenomenon through sampling of the environment so determine the location of events is an important issue in wsn. wireless localization used to determine the position of nodes. the precise localization in wsns is a co...

BACKGROUND The aim of this study was to explore the influence of image-guided tumor localization modality (Synchrony tracking vs. Xsight spine-based localization) on the local efficacy of CyberKnife treatment in lung cancer and lung metastases. METHODS Retrospective analysis of 64 patients with pulmonary metastases and primary tumor cases (72 targets) treated with stereotactic body radiothera...

Sound source localization based on a microphone array for mobile robots faces great challenges because of factors such as uncertainty of the robot’s movement, noise and reverberation, the requirements of a compact microphone array and so on. This paper studies a method for sound source localization in a dynamic environment using a cross‐microphone array plane, which c...
