Transcoding refers to the process of converting HTML files in order to adapt the physical attributes of each device. We call our transcoding “Semantic Transcoding” because it transcodes at the deep semantic level. The proxy server consists of translation, text summarization, video summarization, text-to-speech, speech recognition, and so on. External annotation is also possible. Semantic transc...

This paper proposes a unique computational approach to extraction of expressive elements of motion pictures for deriving high level semantics of stories portrayed, thus enabling better video annotation and interpretation systems. This approach, motivated and directed by the existing cinematic conventions known as film grammar, as a first step towards demonstrating its effectiveness, uses the at...

The rapidly increasing amount of video collections, especially on the web, motivated the need for intelligent automated annotation tools for searching, rating, indexing and retrieval purposes. These videos collections contain all types of manually annotated videos. As this annotation is usually incomplete and uncertain and contains misspelling words, search using some keywords almost do retriev...

In this chapter the authors tackle the analysis and characterization of the artistic animated movies in view of constituting an automatic content-based retrieval system. First, they deal with temporal segmentation, and propose cut, fade and dissolve detection methods adapted to the constraints of this domain. Further, they discuss a fuzzy linguistic approach for automatic symbolic/semantic cont...

The e-learning community has been producing and using video content for a long time, and in the last years, the advent of MOOCs greatly relied on video recordings of teacher courses. Video annotations are information pieces that can be anchored in the temporality of the video so as to sustain various processes ranging from active reading to rich media editing. In this position paper we study ho...

While video has long been used to capture microteaching episodes, illustrate classroom cases and practices, and to review teaching practices, recent developments in video annotation tools may help to extend and augment teacher selfreflection. Such tools make possible the documentation and support self-analysis using verifiable evidence as well as to examine changes in development over time. Vid...

Non-linear video editing was for several years a domain for professionals due to high prices of capture devices and cameras and difficult to use video manipulation software. With the broad availability of cheap video capture and recording devices video editing became popular also in the consumer market. However, software for manipulating digital video is still complicated to use for home users ...

We present a novel error-concealment method for MPEG-2 video decoders. Imperfect transmission of block-based compressed images may result in the loss of blocks, degrading the quality of the received video signal. Since an I-picture is used as a reference picture for forward and backward predictions of neighbouring pictures, transmission errors in an I-picture are propagated both spatially in th...

1 Abstract Software motion pictures is a method of generating digital video on general-purpose desktop computers without using special decompression hardware. The compression algorithm is designed for rapid decompression in software and generates deterministic data rates for use from CD-ROM and network connections. The decompression part offers device independence and integrates well with exist...

The present case-control study investigated the processing of emotional pictures in excessive first-person-shooter-video-players and control persons. All participants of the fMRI experiment were confronted with pictures from four categories including pleasant, unpleasant, neutral content and pictures from the first-person-shooter-video-game 'Counterstrike'. Compared to controls, gamers showed a...
