Latest advancements in online video databases have caused a huge violation of copyright material misuse. Usually a video clip having a proper copyright is available in online video databases like YouTube without permission of the owner. It remains available until the owner takes a notice and requests to the website manager to remove copyright material. The problem with this approach is that usually the copyright material is downloaded and watched illegally during the period of upload and subsequent removal on request of the owner. This study aims at presenting an automatic content based system to detect any copyright violation in online video clips. In this technique, a video clip is needed from original video that is used to query from online video to find out shot similarity based on high level objects like shapes.

Online resources are becoming increasingly important in undergraduate education and have been associated with a number of advantages and positive outcomes on students’ learning experience. However, online resource use by veterinary students for physiology learning remains poorly understood. Thus the present questionnaire-based study aims to investigate the extent to which first- and second-year veterinary students use online resources, including online video clips and social media, in their physiology learning and if this is influenced by factors of age, gender, entry status, or year of study. One-hundred and twenty-two students across seven UK universities completed the survey. Traditional resources (the lecturer and recommended textbooks) were the most preferred sources for physiology learning. Nonetheless, 97.5% of students used Internet search engines to explore physiology topics. Furthermore, students’ tendency to contact their instructor regarding a physiology question was low. Rather, 92.6% said they would first search for an answer online. Particularly popular was the use of online video clips with 91.1% finding them valuable for physiology learning and 34.21% finding them more useful for understanding physiology than university taught material or lecture slides. YouTube was the most common online video clip platform used by students. Most students stated that they would enjoy interacting with course materials on an instructor-led social media page, but only 33.9% currently use social media to discuss physiology-related issues with classmates. Additionally, most students expressed concerns regarding the reliability of online resources but attempts to fact-check these resources were relatively low. Therefore, online resources represent an essential part of veterinary students’ physiology learning and this suggests that educators can significantly improve student engagement and understanding of physiology by integrating these resources.

Interpreting other people’s intentions during communication represents a remarkable challenge for children. Although many studies have examined children’s understanding of, for example, sarcasm, less is known about their interpretation. Using realistic audiovisual scenes, we invited 124 children between 8 and 12 years old to watch video clips of young adults using different speaker intentions. After watching each video clip, children answered questions about the characters and their beliefs, and the perceived friendliness of the speaker. Children’s responses reveal age and gender differences in the ability to interpret speaker belief and social intentions, especially for scenarios conveying teasing and prosocial lies. We found that the ability to infer speaker belief of prosocial lies and to interpret social intentions increases with age. Our results suggest that children at the age of 8 years already show adult-like abilities to understand literal statements, whereas the ability to infer specific social intentions, such as teasing and prosocial lies, is still developing between the age of 8 and 12 years. Moreover, girls performed better in classifying prosocial lies and sarcasm as insincere than boys. The outcomes expand our understanding of how children observe speaker intentions and suggest further research into the development of teasing and prosocial lie interpretation.

Recent advances in software and hardware have allowed eye tracking to move away from static images to more ecologically relevant video streams. The analysis of eye tracking data for such dynamic stimuli, however, is not without challenges. The frame-by-frame coding of regions of interest (ROIs) is labour-intensive and computer vision techniques to automatically code such ROIs are not yet mainstream, restricting the use of such stimuli. Combined with the more general problem of defining relevant ROIs for video frames, methods are needed that facilitate data analysis. Here, we present a first evaluation of an easy-to-implement data-driven method with the potential to address these issues. To test the new method, we examined the differences in eye movements of self-reported politically left- or right-wing leaning participants to video clips of left- and right-wing politicians. The results show that our method can accurately predict group membership on the basis of eye movement patterns, isolate video clips that best distinguish people on the political left–right spectrum, and reveal the section of each video clip with the largest group differences. Our methodology thereby aids the understanding of group differences in gaze behaviour, and the identification of critical stimuli for follow-up studies or for use in saccade diagnosis.

We present an approach to simultaneously reasoning about a video clip and an entire natural-language sentence. The compositional nature of language is exploited to construct models which represent the meanings of entire sentences composed out of the meanings of the words in those sentences mediated by a grammar that encodes the predicate-argument relations. We demonstrate that these models faithfully represent the meanings of sentences and are sensitive to how the roles played by participants (nouns), their characteristics (adjectives), the actions performed (verbs), the manner of such actions (adverbs), and changing spatial relations between participants (prepositions) affect the meaning of a sentence and how it is grounded in video. We exploit this methodology in three ways. In the first, a video clip along with a sentence are taken as input and the participants in the event described by the sentence are highlighted, even when the clip depicts multiple similar simultaneous events. In the second, a video clip is taken as input without a sentence and a sentence is generated that describes an event in that clip. In the third, a corpus of video clips is paired with sentences which describe some of the events in those clips and the meanings of the words in those sentences are learned. We learn these meanings without needing to specify which attribute of the video clips each word in a given sentence refers to. The learned meaning representations are shown to be intelligible to humans.

This research is motivated by the development of the spread of symbols of satanism in the modern era that mushroomed in various mass media, especially video clips to give and deliver messages. One of the top bands named Dewa 19 has symbols associated with symbols of satanism and spread the symbol through the media video clips of the songs of God 19. The focus of this study is the meaning of video clip symbols scattered on each video clip kara band Dewa 19. The theory used is Charles Sanders Peirce Semiotics theory which has a triadic model and trichotomy concept consisting of Representamen, interpretant, and object. The research method used in this research is qualitative research with descriptive type. The results of the research found that the meaning of the symbols scattered in each of the video clips of the band Dewa 19 is the result of the symbolic representation of satanism, among others: Horus's Eye, Pyramid Terpanchung, Chessboard Chess, Photo of Satan Church Founder, God Ra, ANKH SymbolKeywords: semiotics, satanism, Dewa 19, symbols.

This paper is an analysis of a video clip of an interview between a reporter and ice hockey player following a game in which the player was involved in a hard collision with a member of the opposing team. The paper explores blame attribution and how participants claim and disclaim expertise in a way that supports or undermines assertions to have correctly seen and assessed the actions shown on tape. Our analysis focuses on the video of the interview, and it also examines relevant video clips of the collision and various commentaries about the identities of the characters and their actions shown on the videos. In brief, the study is a third-order investigation of recorded-actions-under-analysis. It uses the videos and commentaries as “perspicuous phenomena” that illuminate and complicate how the members’ own action category analysis is bound up with issues of expertise, evidence, and blame.

At Eindhoven University of Technology, which has a modest reputation for collecting contemporary art, an exhibition of large machines and poetic video clips by father and son Van Bakel invites passersby to reflect on mobility. Gerrit van Bakel, who died more than a quarter century ago, became known for his Tarim Machine, a vehicle that moves at such a low speed that it almost does not matter whether it moves or not. The propulsion principle—for those who love technology—rests on the dilatation energy of oil in tubes propelling (if propelling is the right word …) the contraption a couple of centimeters over a hundred years or so, as long as there is change in temperature to trigger the dilatation. Emphasizing his father’s insights, Michiel van Bakel, exhibits a video clip of a horse and rider galloping over a square in Rotterdam, where the position and camera work are operated so that the horse seems to turn around its axis while the environment rotates at a different tempo. Mobility, these Dutch artists convey, is often not what it seems to be.

IntroductionChronic cough in childhood is common and causes much parental anxiety. Eliciting a diagnosis can be difficult as it is a non-specific symptom indicating airways inflammation and this may be due to a variety of aetiologies. A key part of assessment is obtaining an accurate cough history. It has previously been shown that parental reporting of ‘wheeze’ is frequently inaccurate. This study aimed to determine whether parental reporting of the quality of a child’s cough is likely to be accurate.MethodsParents of 48 ‘new’ patients presenting to a respiratory clinic with chronic cough were asked to describe the nature of their child’s cough. They were then shown video clips of different types of cough using age-appropriate examples, and their initial report was compared with the types of cough chosen from the video.ResultsIn a quarter of cases, the parents chose a video clip of a ‘dry’ or ‘wet’ cough having given the opposite description. In a further 20% parents chose examples of both ‘dry’ and ‘wet’ coughs despite having used only one descriptor.DiscussionWhile the characteristics of a child’s cough carry important information that may be helpful in reaching a diagnosis, clinicians should interpret parental reporting of the nature of a child’s cough with some caution in that one person’s ‘dry’ cough may very well be another person’s ‘wet’ cough.

Abstract The use of videos from digital camcorders has become a standard in education in recent years. The curriculum is easily accessible and appeals to a wider audience. The lessons use videos of various physical processes and chemical experiments. However there can be problems with this format. The video quality is often degraded in the final stage when the video is being prepared for placement in education. These include teaching materials in the form of web pages, elearning courses or flash multimedia objects. The final product of editing video from a digital camcorder is a DVD video. However, if we want to transfer this to the Web or other educational material, it is necessary to remove non-square pixels, interlaced video and choose the appropriate compression. For these operations, there are many interpolation algorithms (nearest neighbour, bilinear interpolation, bicubic interpolation), filter deinterlacing (wave, bob, blend), and compression tools. By selecting appropriate settings for these parameters, the video material can be optimized while maintaining the highest possible image quality. The final step before publishing the video is its conversion into one of the used codecs. Codec’s settings will largely impact the final quality and size of the video-clip.
