Single image haze removal using dark channel prior
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
Moving point object data can be analyzed through the discovery of patterns. We consider the
computational efficiency of computing two of the most basic spatio-temporal patterns in …

The optimal sequenced route query
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 …
