Conventional seated audiences have relatively restricted opportunities for response. Perhaps the most salient is applause but they use their hands to make other visible movements: to fix hair, adjust glasses, scratch ears. The question we address here is whether these apparently incidental movements may provide systematic clues about an audience’s level of engagement with a performance. We inve...

Object models based on bag-of-words representations achieve state-of-the-art performance for image classification and object localization. However, as they consider objects as lose collection of information they fail to accurately locate object boundaries and thus produce inaccurate object segmentation. On the other hand, Markov Random Field based models used for image segmentation foFIG. 1 – 4...

The features of an evolutionary algorithm that most determine its performance are the coding by which its chromosomes represent candidate solutions to its target problem and the operators that act on that coding. Also, when a problem involves constraints, a coding that represents only valid solutions and operators that preserve that validity represent a smaller search space and result in a more...

Warning: This draft is draftier than you might expect. More specifically, • Some sections are missing. • Many sections are incomplete. In most cases the incompleteness is noted, but occasionally it isn’t. • Some sections were written nearly two years ago, and are now outdated. • There are not yet enough citations to similar work of other people. Despite all this, there’s probably enough deciphe...

Implicit surfaces have proved to be a particularly well suited and efficient model for animating and morphing shapes of arbitrary topologies. The Blob-Tree model is characterized as a hierarchical combination of skeletal primitives organized in a tree. The nodes hold blending, boolean and warping operators, which allows the design of complex objects. In this paper, we address the metamorphosis ...

Atmospheric turbulence has significant influences on both the trajectories and strengths of wake vortices. In this paper, a quasi-wavelet method is used to generate a random atmospheric turbulence field based on the von Kármán spectrum, in which atmospheric turbulence is represented by groups of random eddies. An inviscid wake vortex system, out-of-ground effect or in-ground effect, is immersed...

In this comment we show that the scaling behaviour of the failure threshold of a random lattice whose individual éléments have a rupture threshold will be différent for the mechanical and electrical problems in percolation conditions. This is due to the fact that only torques and angular distortions are effective in bringing about rupture in the mechanical case. J. Physique 48 (1987) 903-904 J ...

The cytochrome oxidase-rich patches or blobs of the monkey striate cortex have been shown to contain cells that have unoriented receptive fields, many of which are color selective. We studied the functional organization of color opponency in the blob regions of the parafoveal representation of the visual cortex. We also examined the patterns of connectivity among blob and nonblob cells by multi...
