There are many circular-shaped objects in our daily life. Most of these objects usually are deformed and move in both translational and rotational. Under prospective projection, a circle sometimes deformed into an ellipse. Some ellipse-based tracking algorithms can be used tracking the translation when the contour can be extracted automatically, but the rotation can not be extracted. In this paper,...
This paper deals with the problem of performance bound for ground moving extended target tracking with high range resolution ground moving target indicator (HRRGMTI). The system model is constructed for our proposed rectangular target tracking. On performance bounds for state and deterministic shape parameter estimation, a hybrid Cramer-Rao lower bound (CRLB) is proposed and its recursive form is...
The particle filter estimates a probability distribution of target objectpsilas state by sampled hypotheses and their weights. This method is more expressive than existing method such as Kalman filtering, because the object state is represented as a multi-modal distribution. However, the method canpsilat be directly applied to temporally variable appearance object tracking, for example, a firefly...
