Flu Shots, Mammograms, and the Perception of Probabilities We study individuals’ decisions to decline or accept preventive health care interventions such as flu shots and mammograms. In particular, we analyze the role of perceptions of the effectiveness of the intervention, by eliciting individuals’ subjective probabilities of sickness and survival, with and without the interventions. Responden...

An increasing number of applications such as content-based multimedia retrieval in a distributed system and low-bitrate video communications, require the efficient processing and transmission of video information. In content-based video retrieval, video segmentation produces video shots characterized by a certain degree of visual cohesiveness. The number of relevant video shots returned by the ...

This thesis researches the analysis and the formalised metadata mapping of moving data. Therefore a new syntagma for structuring document subparts in movies is being developed. The dissertation focuses on syntagmata which for the first time consider subparts of a document below the shot level. Until now, a set of shots could only be syntagmatically classified, if they were spatially connected. ...

The aim of this study was to examine the behavioural and cranial/spinal responses of alpacas culled by captive bolt shooting and the resulting pathophysiology of captive bolt injury. Ninety-six alpacas were shot (103 shots) in a range of locations with a penetrating captive bolt gun (CBG). Ten (9.8%) alpacas were incompletely concussed following the first shot. No animals required more than two...

We present a surprisingly easy-to-use video browser for helping users to pinpoint a specific video shot in mind, within a long video. At each interactive iteration, the only user effort required is to click 1 shot, which most visually relates to the user’s mental target, out of 8 displayed shots. Then, the system updates the browsing model and display another 8 shots for the next iteration. The...

This paper proposes a novel approach of dominant color based extraction of key frames for sports video summarization. The visual features have been used to obtain play field color shots and non-play field color shots. For the every play field color shots dominant colored key frame has been extracted using color histogram analysis and created video summary. This provides users a way to swiftly b...

We aim at developing a high-performance semantic indexing system using Gaussian-mixture-model (GMM) supervectors and tree-structured GMMs [1, 2, 3]. GMM supervectors corresponding to six types of audio and visual features are extracted from video shots. Tree-structured GMMs reduce the computational cost of maximum a posteriori (MAP) adaptation for estimating GMM parameters while keeping accurac...

Acquired equivalence was investigated using a virtual reality conditioned suppression task administered in a first-person-shooter game. Two visual cues, A1 and B1, were followed by a tone (O1), and another two cues, A2 and B2, were followed by another tone (O2). During differential Pavlovian conditioning, A1 was paired with an instructed unconditioned stimulus (US) consisting of a flashing whit...

This paper presents our method developed for TRECVID 2013 Multimedia Event Detection task. The following two problems are mainly addressed: The first is weakly supervised setting where training videos contain many shots irrelevant to a target event. The other is the diversity of visual appearances, meaning that shots relevant to the event are characterised by significantly different visual appe...

Most information retrieval systems make indirect use of human knowledge in their retrieval process. The novel systems presented here uses the human knowledge directly to retrieve the soccer events. The proposed system is an extended method in three aspects as follows: in the query model, the query by example and query by keywords are applied to retrieve the semantics. In feature extraction, we ...
