In this paper, we describe a new optical tracker algorithm for the tracking of interaction devices in virtual and augmented reality. The tracker uses invariant properties of marker patterns to efficiently identify and reconstruct the pose of these interaction devices. Since invariant properties are sensitive to noise in the 2D marker positions, an off-line training session is used to determine ...

The Multi-feature Beat tracker uses 5 different onsets detection function to estimates the beats of a musical audio signal using only one beat tracker algorithm, finally the beat tracker output is selected using a committee technique presented in previous works. The algorithm ZDG2 get the higher value in five of the ten measures in the Mckinney Dataset in 2012 and the higher AMLt and AMLc value...

We present the warp tracker, a new system for tracking features through a sequence of images. Employing an automated multi-resolution lattice deformation technique, the warp tracker performs fairly well on its own, and its hierarchical nature naturally lends itself to being integrated with other tracking algorithms for increased accuracy and robustness. Developed specifically for use in next-ge...

BACKGROUND The first stage in the implant of a total knee arthroplasty with computer-assisted surgery is to fasten the emitters to the femur and the tibia. These trackers must be hard-fixed to the bone. The objectives of our study are to evaluate the technical problems and complications of these tracker-pins, the necessary time to fix them to the bone and the possible advantages of a new femora...

Abstract The upgraded CMS tracker for HL-LHC is going to require more than 200 kW power. Two different powering strategies are being adopted the Inner Tracker and Outer Tracker. talk describes two schemes discusses their intrinsic constrains. Specifications units cables of systems outlined in combination preliminary results with prototypes.

We describe our Intelligent Star Tracker System. The Intelligent Star Tracker System incorporates an adaptive optic catadioptric telescope in a silicon carbide housing. Leveraging off of our active optic technologies, the novel active pixel position sensors (APPS) enable wide dynamic range and allows simultaneous imagery of faint and bright stars in a single image. Moreover, the APPS, in conjun...
