Wang and Adelson [1] proposed the layer representation as a convenient representation for video coding, format conversion and special effects. We present a technique to extract the near optimal layer representation of an image sequence using the EM algorithm. We incorporate forward / backward motion estimation to obtaina sharp segmentation in the presence of occlusion and uncovering. We demonst...

Date The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned discipline. Run-time optimization defines the process of dynamically modifying an applica-tion's characteristics to promote desirable execution behavior. Since there is a wealth of information avai...

Support vector clustering involves three steps — solving an optimization problem, identification of clusters and tuning of hyperparameters. In this paper, we introduce a pre-processing step that eliminates data points from the training data that are not crucial for clustering. Pre-processing is efficiently implemented using the R*-tree data structure. Experiments on real-world and synthetic dat...

Abstract In this work, we advocate using Bayesian techniques for inversely identifying material parameters multiscale crystal plasticity models. Multiscale approaches modeling polycrystalline materials may significantly reduce the effort necessary characterizing such models experimentally, in particular when a large number of cycles is considered, as typical fatigue applications. Even appropria...

In North America, disturbed riparian zones have had a deleterious effect on the life cycles of anadromous fish, especially commercially and culturally important salmon steelhead. The result has been significant reduction in numbers average size these fish.

Decoupling the uplink and downlink user association improves the throughput of heterogeneous networks (HetNets) and balances the traffic load of macro- and small- base stations. Recently, fiber-wireless HetNets (FiWi-HetNets) have been considered as viable solutions for access networks. To improve the accuracy of user association and resource allocation algorithms in FiWi-HetNets, the capacity ...

test method facet is one of the factors which can have an influence on the test takers’ performance. the purpose of the current study was to investigate the effects of two different response types, multiple-choice cloze and multiple-choice test, on the pre-intermediate and intermediate test takers’ reading comprehension performance. to this end, 40 pre-intermediate and intermediate learners par...

The quality is typically modeled as the univariate or multivariate distribution of quality characteristic/s. In recent applications of statistical process control, quality profiles in which the relationship between a response and explanatory variable/s is captured and monitored are increasingly used to model the quality. Several techniques have been developed to enhance the speed of detecting c...
