X-ray photoelectron and electron energy loss spectroscopic (XPS-EELS) studies reveal that the following species are present when a mixture of CO2 and water vapour is exposed to the clean Mg(100) surface at 110K: CO3(a), C(a) CH(a), OH(a). The reactive chemisorptions of CO2 and H2O vapour coadsorbed on a Mg surface ...

The paper presents a new fast and robust technique of smoke detection in video surveillance images. The approach aims at detecting the spring or the presence of smoke by analyzing color and texture features of moving objects, segmented with background subtraction. The proposal embodies some novelties: first the temporal behavior of the smoke is modeled by a Mixture of Gaussians (MoG ) of the en...

We investigate incorporating structural information from segmentation into a groupwise registration framework. Previous work by Petrovic et al., using MR brain images, showed that using tissue fractions to help construct an intensity reference image gives better results than just using intensity images alone. In their work, a Gaussian Mixture Model (GMM) was fitted to the 1D intensity histogram...

Although the vibration–rotation spectrum of H3O has been studied extensively, there has been no experimental information on the value of the C rotational constant because of the absence of any observed DÉk 0 lÉ x 0 forbidden transitions. However, as pointed out by Verhoeve et al. in their far-infrared spectroscopic work [P. Verhoeve, M. Versluis, J. J. Ter Meulen, W. L. Meerts, and A. Dynamus, ...

Motivated by recent progress in natural image statistics, we use newly available datasets with ground truth optical flow to learn the local statistics of optical flow and compare the learned models to prior models assumed by computer vision researchers. We find that a Gaussian mixture model (GMM) with 64 components provides a significantly better model for local flow statistics when compared to...

In several countries, brick and ceramic tile are the most important construction materials; therefore, associated waste generation is common in demolitions. An alternative use for to incorporate it into road construction. However, biggest limitation as structural pavement layers that strength durability regulatory requirements not met highways when used. As an alternative, demolition (CDW) soil...

Common evaluation standards are critical to making progress in any field, but they can also distort research by shifting all the attention to a limited subset of the problem. Here, we consider the problem of evaluating algorithms for speech separation and acoustic scene analysis, noting some weaknesses of existing measures, and making some suggestions for future evaluations. We take the positio...

We explore the origins of hubs in timbre-based songmodeling in the context of content-based music recommendation and propose several remedies. Specifically, we find that a process of model homogenization, in which certain components of a mixture model are systematically removed, improves performance as measured against several groundtruth similarity metrics. Extending the work of Aucouturier, w...

Existing continuous emotion prediction systems implicitly assume that prediction certainty does not vary with time. However, perception differences among raters and other possible sources of variability suggest that prediction certainty varies with time, which warrants deeper consideration. In this paper, the correlation between the inter-rater variability and the uncertainty of predicted emoti...

Accessing, organizing, and manipulating home videos present technical challenges due to their unrestricted content and lack of storyline. In this paper, we present a methodology to discover cluster structure in home videos, which uses video shots as the unit of organization, and is based on two concepts: 1) the development of statistical models of visual similarity, duration, and temporal adjac...
