Now you see me: evaluating performance in long-term visual tracking [article]

Alan Lukežič, Luka Čehovin Zajc, Tomáš Vojíř, Jiří Matas, Matej Kristan
2018 arXiv   pre-print
We perform an extensive evaluation of six long-term and nine short-term state-of-the-art trackers, using new performance measures, suitable for evaluating long-term tracking - tracking precision, recall  ...  The evaluation shows that a good model update strategy and the capability of image-wide re-detection are critical for long-term tracking performance.  ...  We experimentally show that re-detection capability is critically important for long-term tracking performance. (4) We performed an extensive evaluation of many long-term and short-term trackers in the  ...

2014 Proceedings of the 32nd annual ACM conference on Human factors in computing systems - CHI '14  
We performed a user study (n = 32) to explore how switching sides during authentication affects usability and security of the system.  ...  In this paper, we present XSide, an authentication mechanism that uses the front and the back of smartphones to enter stroke-based passwords.  ...  We performed informal evaluations trying shapes of different complexity and comparing short to long shapes.  ...

Now You See Me: Convolutional Neural Network Based Tracker for Dairy Cows

Oleksiy Guzhva, Håkan Ardö, Mikael Nilsson, Anders Herlin, Linda Tufvesson
2018 Frontiers in Robotics and AI  
In total there were 26 tracks considered, and 23 were correctly tracked.  ...  Experiments indicate that a cow could be tracked close to 4 min before failure cases emerge and that cows could be successfully tracked for over 20 min in mildly-crowded (< 10 cows) scenes.  ...  RESULTS The Performance of "Tracker" Algorithm To evaluate the tracking system, two 1 h recordings were chosen.  ...

Can You See Me Now? Sensor Positioning for Automated and Persistent Surveillance

Yi Yao, Chung-Hao Chen, B. Abidi, D. Page, A. Koschan, M. Abidi
2010 IEEE Transactions on Systems Man and Cybernetics Part B (Cybernetics)  
However, visibility, which is a fundamental requirement of object tracking, is insufficient for automated persistent surveillance.  ...  In this paper, we propose sensor-planning methods that improve existing algorithms by adding handoff rate analysis.  ...  The proposed observation measure gives a quantified evaluation of the tracking and observation suitability, which also agrees with our intuition and visual inspection.  ...

What 'Extended Me' knows

Andy Clark
2015 Synthese  
In this paper, I argue that there is a fundamental tension in these appeals to cognitive virtue.  ...  I examine one such form (rooted in the vision of the 'predictive brain'), and show how it sits neatly with the vision of the extended mind.  ...  It is hard to see how an agent with no access to her own problem-solving procedures could interrogate her own performance in this way.  ...

The six developed Engagement Catalysers have been used and evaluated in two workshops, in which participants from very different cultural and professional background have used them as a means to engage  ...  The results show that the Catalysers stimulate engagement, help people to get familiar and connected in a short period of time, and seem to inspire and boost the design process.  ...  Moreover, we like to thank the City of Eindhoven for financially supporting WS1 and Necker van Naem and the Ministry of Interior and Kingdom Relations for their effort and support in WS2.  ...
