- The Visual Object Tracking challenge VOT2020 is the eighth annual tracker benchmarking activity organized by the VOT initiative. Results of 58 trackers are presented; many are state-of-the-art trackers published at major computer vision conferences or in journals in the recent years. The VOT2020 challenge was composed of five sub-challenges focusing on different tracking domains: (i) VOT-ST2020 challenge focused on short-term tracking in RGB, (ii) VOT-RT2020 challenge focused on “real-time” short-term tracking in RGB, (iii) VOT-LT2020 focused on long-term tracking namely coping with target disappearance and reappearance, (iv) VOT-RGBT2020 challenge focused on short-term tracking in RGB and thermal imagery and (v) VOT-RGBD2020 challenge focused on long-term tracking in RGB and depth imagery. Only the VOT-ST2020 datasets were refreshed. A significant novelty is introduction of a new VOT short-term tracking evaluation methodology, and introduction of segmentation ground truth in the VOT-ST2020 challenge – bounding boxes will no longer be used in the VOT-ST challenges. A new VOT Python toolkit that implements all these novelites was introduced. Performance of the tested trackers typically by far exceeds standard baselines. The source code for most of the trackers is publicly available from the VOT page. The dataset, the evaluation kit and the results are publicly available at the challenge website (http://votchallenge.net ).

A peer to peer architecture for enabling a universal presence service
- 2010

Ingår i: Proceedings - NGMAST 2010. - 9780769541211 ; , s. 90-95

Konferensbidrag (refereegranskat)abstract
- Presence service is used to publish and discover end-users' context information. It is the basis of a wide range of end-user services. It is deployed using a wide range of technologies, which hampers interoperability. This paper proposes a peer to peer infrastructure for enabling a universal presence service, a service that will enable end users with multiple presence accounts in domains with different technologies to publish and discover end-user context information through a single interface. Requirements are derived, an architecture is proposed and implementation aspects are discussed. The architecture is an overlay and the related procedures and protocols are introduced. New software architecture is proposed for the implementation and the related tool kits are identified.

Parametric Continuous-Time Blind System Identification
- 2023

Konferensbidrag (refereegranskat)abstract
- In this paper, the blind system identification problem for continuous-time systems is considered. A direct continuous-time estimator is proposed by utilising a state-variable-filter least squares approach. In the proposed method, coupled terms between the numerator polynomial of the system and input parameters appear in the parameter vector which are subsequently separated using a rank-1 approximation. An algorithm is then provided for the direct identification of a single-input single-output linear time-invariant continuous-time system which is shown to satisfy the property of correctness under some mild conditions. Monte Carlo simulations demonstrate the performance of the algorithm and verify that a model and input signal can be estimated to a proportion of their true values.

A simplified adaptive modulation scheme for RSOA based DDO-OFDM system using CAZAC precoding
- 2016

Ingår i: 2016 Optical Fiber Communications Conference and Exhibition, OFC 2016. - Washington, D.C. : Institute of Electrical and Electronics Engineers (IEEE).

Konferensbidrag (refereegranskat)abstract
- We experimentally demonstrated a RSOA based DDO-OFDM system using CAZAC precoding. Adaptive modulation has been simply and efficiently performed after CAZAC precoding to improve the sensitivity and overall data rate thanks to the equalized SNR.
