Event retrieval using motion barcodes [PDF]

2015 IEEE International Conference on Image Processing (ICIP), 2015
We introduce a simple and effective method for retrieval of videos showing a specific event, even when the videos of that event were captured from significantly different viewpoints. Appearance-based methods fail in such cases, as appearances change with large changes of viewpoints.

Motion in event structure

Acta Linguistica Hafniensia
According to a localist theory of event semantics, event types such as state changes and realisation of actions are based on motion events, which are taken to be the primary type of event. The present paper investigates some claims of this theory, their consequences and conceptual foundations. It argues that the theory suffers from two flaws.

Event-Based Motion Magnification [PDF]

Detecting and magnifying imperceptible high-frequency motions in real-world scenarios has substantial implications for industrial and medical applications. These motions are characterized by small amplitudes and high frequencies. Traditional motion magnification methods rely on costly high-speed cameras or active light sources, which limit the scope of

Independent motion detection with event-driven cameras [PDF]

2017 18th International Conference on Advanced Robotics (ICAR), 2017
Unlike standard cameras that send intensity images at a constant frame rate, event-driven cameras asynchronously report pixel-level brightness changes, offering low latency and high temporal resolution (both in the order of micro-seconds). As such, they have great potential for fast and low power vision algorithms for robots.

The encoding of motion events

, 2013
This chapter investigates eleven fundamental questions of motion event encoding from a massively cross-linguistic (i.e. typological) perspective in a bottom-up approach in parallel and original texts making use of quantitative and qualitative methods and various visualization methods.

Motion Deblurring with Real Events [PDF]

2021 IEEE/CVF International Conference on Computer Vision (ICCV), 2021
In this paper, we propose an end-to-end learning framework for event-based motion deblurring in a self-supervised manner, where real-world events are exploited to alleviate the performance degradation caused by data inconsistency. To achieve this end, optical flows are predicted from events, with which the blurry consistency and photometric consistency

Co-event relations in Swedish motion constructions

, 2022
This paper discusses co-events denoted by verbs used in Swedish motion events. The motion events are analyzed as constructions in the sense of construction grammar, in which the motion component can be argued to be evoked by a syntactic construction ...

Intratypological differences in motion event descriptions : information packaging and information density in L1 and L2 acquisition

, 2021
Cross-linguistic differences in motion event descriptions are well documented, regarding information focus (which elements of the motion event are typically selected for verbalization) and information locus (which linguistic means are typically used for ...

Event-related alpha suppression in response to facial motion [PDF]

, 2014
This article has been made available through the Brunel Open Access Publishing Fund.While biological motion refers to both face and body movements, little is known about the visual perception of facial motion. We therefore examined alpha wave suppression

The Timing of Feedback to Early Visual Cortex in the Perception of Long-Range Apparent Motion [PDF]

, 2008
When 2 visual stimuli are presented one after another in different locations, they are often perceived as one, but moving object. Feedback from area human motion complex hMT/V5+ to V1 has been hypothesized to play an important role in this illusory ...
