Efficient keyframe-based real-time camera tracking
We present a novel keyframe-based global localization method for markerless real-time camera tracking. Our system contains an offline module to select features from a group of reference images and an online module to match them to the input live video for quickly estimating the camera pose. The main contribution lies in constructing an optimal set of keyframes from the input reference images, w...
متن کاملDistributed Radar Network for Real-Time Tracking of Bullet Trajectory
Gunshot detection, sniper localization, and bullet trajectory prediction are of significant importance in military and homeland security applications. While the majority of existing work is based on acoustic and electro-optical sensors, this paper develops a framework of networked radar systems that uses distributed radar sensor networks to achieve the abovementioned objectives. The use of radi...
متن کاملReal-Time Interference Detection in Tracking Loop of GPS Receiver
Global Positioning System (GPS) spoofing could pose a major threat for GPS navigation ‎systems, so the GPS users have to gain a better understanding of the broader implications of ‎GPS.‎ In this paper, a plenary anti-spoofing approach based on correlation is proposed to distinguish spoofing effects. The suggested ‎method can be easily implemented in tracking loop of GPS receiver...
متن کاملEfficient Adaptive Combination of Histograms for Real-Time Tracking
We quantitatively compare two template-based tracking algorithms, Hager’s method and the hyperplane tracker, and three histogram-based methods, the mean-shift tracker, two trust-region trackers, and the CONDENSATION tracker. We perform systematic experiments on large test sequences available to the public. As a second contribution, we present an extension to the promising first two histogram-ba...
متن کاملEfficient Real-Time Face Tracking in Wavelet Subspace
In this article we present a new method for visual face tracking that is carried out in wavelet subspace. Firstly, a wavelet representation for the face template is created, which spans a low-dimensional subspace of the image space. The video sequence frames where the face is tracked are then orthogonally projected into this low-dimensional subspace. This can be done efficiently through a small...
