On event-based motion detection and integration

Proceedings of the 8th International Conference on Bio-inspired Information and Communications Technologies (formerly BIONETICS), 2015
Event-based vision sensors sample individual pixels at a much higher temporal resolution and provide a representation of the visual input available in their receptive fields that is temporally independent of neighboring pixels. The information available on pixel level for subsequent processing stages is reduced to representations of changes in the ...

Timing of visual events for motion discrimination

Vision Research, 1994
The observer's task was to identify the temporal order of the two adjacent luminance excursions one of which was a step-function and the other a linear increase in luminance starting from zero and reaching various final amplitude A after some period of time D.

Event-by-event motion compensation in 3D PET

2003 IEEE Nuclear Science Symposium. Conference Record (IEEE Cat. No.03CH37515), 2004
Motion compensation in brain PET using a multiple acquisition frame (MAF) method in conjunction with an optical motion tracking system has been previously described. The MAF method is applicable to multi-frame PET data acquired dynamically, and also to list mode data that have been sorted into multiple frames.

Event‐by‐event respiratory motion correction for PET with 3D internal‐1D external motion correlation

Medical Physics, 2013
Purpose: Respiratory motion during PET/CT imaging can cause substantial image blurring and underestimation of tracer concentration for both static and dynamic studies. In this study, the authors developed an event‐by‐event respiratory motion correction method that used

The Typology of Motion Events

2013
This comprehensive study concentrates particularly on the use of a closed set of motion verbs in five of the major dialects, including Mandarin, Wu, Hakka, M?n and Cantonese. The author shows that these dialects form a continuum with some exhibiting more characteristics of a verb-framed language than the others.

Motion and Discontinuity Events

2001
In this chapter we discuss discontinuity events that might occur in non-smooth mechanics. In particular, these are jumps in the velocities, usually associated with collisions and treated within impact theory, but also jumps in the accelerations as they appear, for example, at the transitions from sliding to stiction when dry friction is prevalent ...

Motion events in Bambara (Mande)

Journal of African Languages and Linguistics, 2012
The paper analyses motion events in the Mande language Bambara, using the theoretical framework developed by Croft et al. (2010), which is a revision of the theory first proposed by Talmy (1975, 1985). The revision of Talmy's theory on the semantics and syntax of motion events introduces a distinction between symmetrical and asymmetrical constructions ...

Metaphictive Motion Events

2005
Relying upon the notions of space and motion in their correlation with language and human cognition, the paper will place the focus upon the metaphorical extension of motion verbs in their combinatorial semantics with nouns referring to mental activities.
