Embedded Block Coding with Optimal Truncation (EBCOT) is the fundamental and computationally very demanding part of the compression process of JPEG2000 image compression standard. In this paper, we present a refor-mulation of the context modeling of EBCOT that allows full parallelization for massively parallel architectures such as GPUs with their single(More)
Particles in the atmosphere are of concern due to their toxic properties and effects on climate. In coastal areas, ship emissions can be a significant anthropogenic source. In this study we investigated the contribution from ship emissions to the total particle number and mass concentrations at a remote location. We studied the particle number concentration(More)
Prior work on videoconferencing shows that various design changes can have profound impacts on group dynamics. In order to further explore the available design space, we report on a qualitative study that compares behaviour of groups in two group-to-group videoconferencing environments and face-to-face communication during a complex social dilemma game.(More)
Embedded Block Coding with Optimal Truncation (EBCOT) is the fundamental and compu-tationally very demanding part of the compression process of JPEG2000 image compression standard. EBCOT itself consists of two tiers. In Tier-1, image samples are compressed using context modeling and arithmetic coding. Resulting bit-stream is further formated and truncated(More)
