The absence of a commonly adopted performance evaluation framework is hampering advances in the design of effective video trackers. In this paper, we present a single-score evaluation measure and a protocol to objectively compare trackers. The proposed measure evaluates tracking accuracy and failure, and combines them for both summative and formative(More)
We present an end-to-end approach for trajectory clustering from aerial videos that enables the extraction of motion patterns in urban scenes. Camera motion is first compensated by mapping object trajectories on a reference plane. Then clustering is performed based on statistics from the Discrete Wavelet Transform coefficients extracted from the(More)
To evaluate multitarget video tracking results, one needs to quantify the accuracy of the estimated target-size and the cardinality error as well as measure the frequency of occurrence of ID changes. In this paper, we survey existing multitarget tracking performance scores and, after discussing their limitations, we propose three parameter-independent(More)
The growing interest in developing video tracking algorithms has not been accompanied by the development of commonly used evaluation criteria to assess and to compare their performance. Researchers often present trackers' results on different datasets and evaluate them with different performance measures thus hindering both formative and summative quality(More)
Many approaches have been considered for automatic grading of brain tumors by means of pattern recognition with magnetic resonance spectroscopy (MRS). Providing an improved technique which can assist clinicians in accurately identifying brain tumor grades is our main objective. The proposed technique, which is based on the discrete wavelet transform (DWT)(More)
This paper presents the two datasets (ARENA and P5) and the challenge that form a part of the PETS 2015 workshop. The datasets consist of scenarios recorded by using multiple visual and thermal sensors. The scenarios in ARENA dataset involve different staged activities around a parked vehicle in a parking lot in UK and those in P5 dataset involve different(More)
We report an unusual case of endocarditis caused by Neisseria elongata subsp. elongata. The illness was complicated by a ruptured mycotic aneurysm of the right brachial artery, with compression of the brachial plexus. A cure was achieved after aneurysm resection and treatment with intravenous ceftriaxone and gentamicin.
Energy Managers and Government Office Holders in Pakistan are nowadays pondering over multiple options for the resolution of ongoing Energy crises in the country. LNG (Liquefied Natural Gas) import has been finalized for being the quickest remedy among all the available options. LNG (Liquefied Natural Gas) contract is at the verge to be implemented in(More)
