thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
As an extension of the work of Kuo et al[l], we have developed a "Flying-Spot" lasersource/IR-detector camera in which the focal point of an unmodulated heating laser is moved at constant velocity across the sample while the image point of an IR detector is scanned at the same speed at a point just behind the laser beam. The detector is thus looking at the "thermal wake" of the heated spot. The...
A technique for building a three-dimensional description of a static scene from a spatiotemporal image is presented. This technique utilizes Homocentric Spherical Spatiotemporal Image (HSSI) analysis and makes allowances for camera rotation, which is a wider class of camera motion than that in ordinary spatiotemporal image analysis. Experiments with real images from a translating and rotating c...
The main purpose of this project is to nominate the places of a view taken by a panoramic camera. The problematic is to know where the place will be projected on the image. A camera model has to be established in order to transform the real points from the three dimensional world coordinates into the image point in two dimensional screen coordinates.
introduction: the use of multiple cameras for motion analysis and single joint motion is very difficult and needs high technology in laboratory conditions. detection of single joint motion in kinesthesia and analysis of its changes can be done by one camera at one direction. in this study, we present the validity and reliability of a new prototype simulator system used for motion analysis appli...
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...
Camera calibration is a process to find camera parameters. Camera parameter consists of intrinsic and extrinsic configuration and it is important to deal with the three-dimensional (3-D) geometry of the cameras and 3-D scene. However, camera calibration is quite annoying process when the number of cameras and images increase because it is operated by hand to indicate exact points. In order to e...
