The `1 tracker obtains robustness by seeking a sparse representation of the tracking object via `1 norm minimization [1]. However, the high computational complexity involved in the `1 tracker restricts its further applications in real time processing scenario. Hence we propose a Real Time Compressed Sensing Tracking (RTCST) by exploiting the signal recovery power of Compressed Sensing (CS). Dim...

Abstract: In this paper, we present the use of the laser tracker to aid the alignment of a Swing Arm Profilometer (SAP) and measure the length of the swinging arm, thus calibrating the operating radius of the SAP. The measurement uncertainty analysis is given. A laser tracker is used to align the SAP to ensure the path of the probe head passes through the rotary axis of the rotary table. By bui...

Long-term tracking requires extreme stability to the multitude of model updates and robustness to the disappearance and loss of the target as such will inevitably happen. For motivation, we have taken 10 randomly selected OTBsequences, doubled each by attaching a reversed version and repeated each double sequence 20 times. On most of these repetitive videos, the best current tracker performs wo...

Online tracking poses a serious privacy challenge that has drawn significant attention in both academia and industry. Existing approaches for preventing user tracking, based on curated blocklists, suffer from limited coverage and coarsegrained resolution for classification, rely on exceptions that impact sites’ functionality and appearance, and require significant manual maintenance. In this pa...

The ML-PMHT MultistaticTracker for SharplyManeuvering Targets Report Title The maximum likelihood probabilistic multi-hypothesis tracker (ML-PMHT) is applied to a benchmark multistatic active sonar scenario with multiple targets, multiple sources, and multiple receivers. We first compare the performance of the tracker on this scenario when it is applied in Cartesian measurement space, a typical...

Trackers are used in peer-to-peer (P2P) networks for provider discovery, that is, mapping resources to potential providers. Centralized trackers, e.g., as in the original BitTorrent protocol, do not benefit from P2P properties, such as no single point of failure, scalability, and load balancing. Decentralized mechanisms have thus been proposed, based on distributed hash tables (DHTs) and gossip...
