Over the past decade, evolution of video-sharing platforms has attracted a significant amount investments on contextual advertising. The common advertising utilize information provided by users to integrate 2D visual ads into videos. existing face many technical challenges such as ad integration with respect occluding objects and 3D placement. This paper presents Video Advertisement Placement &...

PURPOSE The conformity of the achieved dose distribution to the treatment plan strongly correlates with the accuracy of seed implantation in a prostate brachytherapy treatment procedure. Incorrect seed placement leads to both short and long term complications, including urethral and rectal toxicity. The authors present BrachyView, a novel concept of a fast intraoperative treatment planning syst...

Virtual camera control is a key factor in game experience because the camera dictates how players see the game world. As the complexity and unpredictability of games increases, automatic camera control becomes a fundamental requirement. In this paper, we present a game technology demonstrator that showcases automatic camera control capable of creating dissimilar experiences within a 3D prey/pre...

A micron-precision optical alignment system (OASys) for the PHENIX muon tracking chambers is developed. To ensure the required mass resolution of vector meson detection, the relative alignment between three tracking station chambers must be monitored with a precision of 25μm. The OASys is a straightness monitoring system comprised of a light source, lens and CCD camera, used for determining the...

If it is impossible to capture all the image in one scan with the available equipment, a montage can be made from separately scanned pieces. We describe an automatic mosaicing process for document images. The image shifts are found by a correlation technique, using an image pyramid and sequential similarity to reduce computation time. Image placement and overlap is used to reject incorrect solu...

This paper describes the design and construction of a wearable active vision platform which is able to achieve substantial decoupling of the camera motion from the wearer’s motion. Design issues in sensor placement, robot kinematics and their relation to wearability are discussed and the prototype platform’s performance is evaluated in a number of important visual tasks. The paper also discusse...

This paper deals a review of the uncertainty modeling in the placement of work space fixtures, say a container in the work space environment of the robot to do a particular task, i.e., to insert or remove some of the manufactured components from the bin or the container. The uncertainty model shown in this paper makes a compromise between the optical distortion using a camera and the robot prec...

Abstract Introduction Inflatable penile prosthesis reservoir herniation or migration may occur with space of Retzius submuscular placement. The dangers high placement include bowel bladder perforation (from blind instrument passage) and unintentional peritoneal stretching small opening filling). Even under direct vision placement, reservoirs can ultimately reside into the scrotum, retroperitone...

Surgical cameras are prevalent in modern operating theatres and are often used as a surrogate for direct vision. Visualisation techniques (e.g. image fusion) made possible by tracking the camera require accurate hand-eye calibration between the camera and the tracking system. The authors introduce the concept of 'guided hand-eye calibration', where calibration measurements are facilitated by a ...

OBJECTIVE The objective of this study was to evaluate whether the use of a video double-lumen tube reduced the need for fiberoptic bronchoscopy for (1) verification of initial tube placement and for (2) reverification of correct placement after repositioning for thoracotomy. DESIGN A single-center retrospective study. SETTING Thoracic surgery in a medical university hospital. PARTICIPANTS...
