    Sammanfattning : A large amount of the information in conversations come from non-verbal cues such as facial expressions and body gesture. These cues are lost when we don't communicate face-to-face. But face-to-face communication doesn't have to happen in person. With video communication we can at least deliver information about the facial mimic and some gestures. LÄS MER

  2. 2. Very low bitrate facial video coding based on principal component analysis

    Detta är en avhandling från Umeå : Tillämpad fysik och elektronik

    Författare :Ulrik Söderström; Umeå universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Image processing; Video processing; Very low bitrate coding; TECHNOLOGY Electrical engineering; electronics and photonics Other electrical engineering; electronics and photonics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Övrig elektroteknik; elektronik och fotonik;

    Sammanfattning : This thesis introduces a coding scheme for very low bitrate video coding through the aid of principal component analysis. Principal information of the facial mimic for a person can be extracted and stored in an Eigenspace. Entire video frames of this persons face can then be compressed with the Eigenspace to only a few projection coefficients. LÄS MER

  3. 3. Application of automated video analysis to road user behaviour

    Detta är en avhandling från Umeå : Tillämpad fysik och elektronik

    Författare :Aliaksei Laureshyn; Lunds universitet.; Lund University.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; safety indicators; traffic safety; traffic conflicts; Video analysis; road user behaviour;

    Sammanfattning : The successful planning, design and management of a traffic system is impossible without knowledge of how the traffic environment affects the behaviour of road users and how the behaviour is related to the main qualities of the traffic system (e.g. safety, efficiency). LÄS MER

  4. 4. Natural language processing in cross-media analysis

    Detta är en avhandling från Umeå : Department of computing science, Umeå University

    Författare :Yonas Demeke Woldemariam; Umeå universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NLP; cross-media analysis; sentiment analysis; competence analysis; speech recognition; Amharic; named entity recognition; machine learning; computational linguistics; Computer Science; datalogi;

    Sammanfattning : A cross-media analysis framework is an integrated multi-modal platform where a media resource containing different types of data such as text, images, audio and video is analyzed with metadata extractors, working jointly to contextualize the media resource. It generally provides cross-media analysis and automatic annotation, metadata publication and storage, searches and recommendation services. LÄS MER

    Detta är en avhandling från Växjö : Linnaeus University Press

    Författare :Sofia Backåberg; Linnéuniversitetet.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Activity limitation; ergonomics; hermeneutics; interactive learning; musculoskeletal system; observational movement analysis; phenomenological hermeneutics; qualitative content analysis; reflection; video feedback; Vårdvetenskap; Caring Science;

    Sammanfattning : Aim:  The overall aim of this thesis was to explore the development of a video-supported interactive learning model for movement awareness among nursing students.Methods:  Study I was a cross-sectional survey regarding prevalence and impact of musculoskeletal symptoms (MSS) among nursing students.
