In this paper, we describe a statistical method to detect highlights in a baseball game video. The input video is first segmented into scene shots, within which the camera motion is continuous. Our approach is based on the observations that 1) most highlights in baseball games are composed of certain types of scene shots and 2) those scene shots exhibit special transition context in time. To ex...

We propose tools and methods to track visual memes on community-centric rich-media repositories, such as YouTube. Visual memes refer to frequently reposted short video segments. Our method can be used to monitor the reflections of real-world events in rich media, including images and videos. We first design a large-scale event-based social video collection system to continuously monitor events ...

We present an open-source web-based multimodal dialog framework, “Multimodal HALEF”, that integrates video conferencing and telephony abilities into the existing HALEF cloud-based dialog framework via the FreeSWITCH video telephony server. Due to its distributed and cloud-based architecture, Multimodal HALEF allows researchers to collect video and speech data from participants interacting with ...

A new computer software program to score video observations, Video Observations Aarts and Aarts (VOAA) was developed to evaluate paediatric occupational therapy interventions. The VOAA is an observation tool that assesses the frequency, duration and quality of arm/hand use in children, in particular those with cerebral palsy. Reliability studies show that the first module, designed to evaluate ...

Distributed organizations increasingly rely on new video-supported communication technologies that may be subject to transmission delays. These delays systematically misalign the feedback one side receives from the other. Through microanalysis of video data from a video-supported' meeting in a geographically distributed company, we examine the impact of delay in such communication systems We sp...
