Single image haze removal using dark channel prior

K He, J Sun, X Tang - IEEE transactions on pattern analysis …, 2010 - ieeexplore.ieee.org
In this paper, we propose a simple but effective image prior-dark channel prior to remove
haze from a single input image. The dark channel prior is a kind of statistics of outdoor haze …

Computing longest duration flocks in trajectory data

J Gudmundsson, M Van Kreveld - Proceedings of the 14th annual ACM …, 2006 - dl.acm.org

computational efficiency of computing two of the most basic spatio-temporal patterns in …

Casper* query processing for location services without compromising privacy

CY Chow, MF Mokbel, WG Aref - ACM Transactions on Database …, 2009 - dl.acm.org
In this article, we present a new privacy-aware query processing framework, Capser*, in
which mobile and stationary users can obtain snapshot and/or continuous location-based …

The optimal sequenced route query

M Sharifzadeh, M Kolahdouzan, C Shahabi - The VLDB journal, 2008 - Springer
Real-world road-planning applications often result in the formulation of new variations of the
nearest neighbor (NN) problem requiring new solutions. In this paper, we study an …

Trajectory pattern mining

H Jeung, ML Yiu, CS Jensen - Computing with spatial trajectories, 2011 - Springer
In step with the rapidly growing volumes of available moving-object trajectory data, there is
also an increasing need for techniques that enable the analysis of trajectories. Such …

Clustering algorithm for network constraint trajectories

A Kharrat, IS Popa, K Zeitouni, S Faiz - Headway in Spatial Data Handling …, 2008 - Springer
Spatial data mining is an active topic in spatial databases. This paper proposes a new
clustering method for moving object trajectories databases. It applies specifically to …

Mixed-drove spatiotemporal co-occurrence pattern mining

M Celik, S Shekhar, JP Rogers… - IEEE Transactions on …, 2008 - ieeexplore.ieee.org
Mixed-drove spatio-temporal co-occurrence patterns (MDCOPs) represent subsets of two or
more different object-types whose instances are often located in spatial and temporal …

Symbolic trajectories

RH Güting, F Valdés, ML Damiani - ACM Transactions on Spatial …, 2015 - dl.acm.org
Due to the proliferation of GPS-enabled devices in vehicles or with people, large amounts of
position data are recorded every day and the management of such mobility data, also called …

A novel distributed framework for optimizing query routing trees in wireless sensor networks via optimal operator placement

G Chatzimilioudis, A Cuzzocrea, D Gunopulos… - Journal of Computer and …, 2013 - Elsevier
In this paper, we focus the attention on the operator placement problem in Wireless Sensor
Networks (WSN). This problem is very relevant for in-network query processing over WSN …
