Performance Measures and a Data Set for Multi-target, Multi-camera Tracking

Abstract: To help accelerate progress in multi-target, multi-camera tracking systems, we present (i) a new pair of precision-recall measures of performance that treats errors of all types uniformly and emphasizes correct identification over sources of error; (ii) the largest fully-annotated and calibrated data set to date with more than 2 million frames of 1080 p, 60 fps video taken by 8 cameras observing more than 2,700 identities over 85 min; and (iii) a reference software system as a comparison baseline. We show that (i) our measures properly account for bottom-line identity match performance in the multi-camera setting; (ii) our data set poses realistic challenges to current trackers; and (iii) the performance of our system is comparable to the state of the art.

Global Strategy for the Diagnosis, Management and Prevention of COPD: 2003 update

Abstract: The Global Initiative for Chronic Obstructive Lung Disease (GOLD) programme was initiated in January 1997 to increase awareness of chronic obstructive pulmonary disease (COPD) and to decrease morbidity and mortality from this chronic lung disorder. One strategy to help achieve the objectives of the GOLD programme is to provide healthcare workers, healthcare authorities and the general public with state-of-the-art information about COPD and specific recommendations on the most appropriate management and prevention strategies. The GOLD Workshop Report, Global Strategy for the Diagnosis, Management and Prevention of COPD 1 was published in April 2001. It was prepared by a panel of experts nominated by the National Heart, Lung and Blood Institute (NHLBI), National Institutes of Health and the World Health Organization with the aim of providing the best validated current concepts of COPD pathogenesis and the best available evidence on the most appropriate management and prevention strategies. In an effort to keep the GOLD Workshop Report as up to date as possible, GOLD assembled a Scientific Committee whose aim was to review clinical research that has an impact on COPD management. The initial review included publications that were published in June 2000 (approximately the time of completion of the 2001 report) through to March 2003. The results of the first 2 yrs of activity were posted on the GOLD website (www.goldcopd.com) in July 2003 2. Each year, a new update report will be posted. The GOLD Scientific Committee will also prepare a revision of the entire GOLD Workshop Report approximately every 5 yrs. The process for the first complete revision (to appear in 2006) will be developed in the autumn of 2003. The process included a PubMed search using search fields established by the GOLD Scientific Committee: 1) COPD OR chronic bronchitis OR emphysema, All Fields, All Adult, 19+ yrs, only items …

Visual Tracking: An Experimental Survey

Abstract: There is a large variety of trackers, which have been proposed in the literature during the last two decades with some mixed success. Object tracking in realistic scenarios is a difficult problem, therefore, it remains a most active area of research in computer vision. A good tracker should perform well in a large number of videos involving illumination changes, occlusion, clutter, camera motion, low contrast, specularities, and at least six more aspects. However, the performance of proposed trackers have been evaluated typically on less than ten videos, or on the special purpose datasets. In this paper, we aim to evaluate trackers systematically and experimentally on 315 video fragments covering above aspects. We selected a set of nineteen trackers to include a wide variety of algorithms often cited in literature, supplemented with trackers appearing in 2010 and 2011 for which the code was publicly available. We demonstrate that trackers can be evaluated objectively by survival curves, Kaplan Meier statistics, and Grubs testing. We find that in the evaluation practice the F-score is as effective as the object tracking accuracy (OTA) score. The analysis under a large variety of circumstances provides objective insight into the strengths and weaknesses of trackers.

Going from evidence to recommendations

Abstract: The GRADE system classifies recommendations made in guidelines as either strong or weak. This article explores the meaning of these descriptions and their implications for patients, clinicians, and policy makers
