Quadratic Programming for Multi-Target Tracking

, 2009
We consider the problem of tracking multiple, partially observed targets using multiple sensors arranged in a given configuration. We model the problem as a special case of a (finite horizon) DEC-POMDP. We present a quadratic program whose globally optimal solution yields an optimal tracking joint policy, one that maximizes the expected targets ...

Content-aware foveated camera for multi-target tracking

Optics Express
Modern image sensors deliver substantial space-time bandwidth, yet indiscriminate acquisition often overwhelms memory, computation, and downstream perception. We present a content-aware, multi-foveated camera that dynamically reallocates sensing and magnification to multiple regions of interest (ROIs).

An anti-occlusion optimization algorithm for multiple pedestrian tracking.

PLoS ONE
Frequent occlusion of tracking targets leads to poor performance of tracking algorithms. A common practice in multi-target tracking algorithms is to re-identify the occluded tracking targets, which increases the number of identity switching occurrences ...
