The present study examined the way in which the perception of motion coherency depends on luminance contrast. Pseudo-plaid patterns were presented to subjects who judged whether coherent motion or component motion of the Gabor patterns was perceived. Michelson contrast, eccentricity, spatial separation, and angular separation between two groups of Gabor patches were varied systematically. When ...

This study disentangled the influences of language and social processing on communication in autism spectrum disorder (ASD) by examining whether gesture and speech production differs as a function of social context. The results indicate that, unlike other adolescents, adolescents with ASD did not increase their coherency and engagement in the presence of a visible listener, and that greater coh...

The deuteride ~hydride! precipitation and decomposition microstructure in single-crystal Pd has been investigated in a series of in situ small-angle neutron scattering ~SANS! measurements. The particle morphology along the absorption and desorption branches of the 353-K pressure-composition isotherm are consistent with a loss of particle coherency, leading to the formation of large, micron-thic...

The objective evaluation of 2D-shape estimation results for moving objects in a video sequence is still an open problem. First approaches in the literature evaluate the spatial accuracy and the temporal coherency of the estimated 2D object shape. Thereby, it is not distinguished between several estimation errors located around the object contour and a few, but larger, estimation errors. Both ca...
