For the complex combat environment, considering the flyable performance constrains and the safety constrains, an online trajectory planning algorithm of UAVs(Unmanned Aerial Vehicles) based on Pythagorean Hodograph (PH) curve is put forward, which is easy to traced. When the unexpected obstacles are detected, based on the velocity obstacles avoidance method, the collision avoidance trajectory i...

We derive a probabilistic framework for robust, real-time, visual tracking of previously unseen objects from a moving camera. The tracking problem is handled using a bag-of-pixels representation and comprises a rigid registration between frames, a segmentation and online appearance learning. The registration compensates for rigid motion, segmentation models any residual shape deformation and th...

In this paper, we present an interactive augmented reality (AR) game for tracking a remotecontrolled car controlled by players. We propose it as a new markerless framework for tracking a colored remote-controlled car by integrating a Bayesian classifier into particle filters. This adds the useful abilities of automatic track initiation and recovery from tracking failures in a cluttered backgrou...

We propose an efficient online real-time solution for singlecamera 3–D tracking of rigid objects that can handle large camera displacements, drastic aspect changes, and partial occlusions. While the offline camera registration problem can be considered as essentially solved, robust online tracking remains an open issue because many real-time algorithms described in the literature still lack rob...

Accurate real-time tracking of influenza outbreaks helps public health officials make timely and meaningful decisions that could save lives. We propose an influenza tracking model, ARGO (AutoRegression with GOogle search data), that uses publicly available online search data. In addition to having a rigorous statistical foundation, ARGO outperforms all previously available Google-search-based t...

False matching due to errors in feature extraction and changes in illumination between frames may occur in feature tracking in image sequences. False matching leads to outliers in feature motion trajectory. One way of reducing the effect of outliers is stochastic filtering using a state space model for motion trajectory. Hyper-parameters in the state space model, e.g., variances of noise distri...

Target modeling and model fitting are the two important parts of the problem of object tracking. The former has to provide a good reference for the latter. Online appearance models (OAM) has been successfully used for facial features tracking on account of their strong ability to adapt to variations, however, it suffers from time-consuming model fitting. Inverse Compositional Image Alignment (I...

The Student Online Project Planning and Tracking System, SOPPTS, is an online system designed and implemented to enhance the communication avenues and the project planning/tracking requirements of student projects for the Ball State University (BSU) software engineering classes. This paper presents the design and assessment of this tool. SOPPTS has been designed and field-tested to provide real...
