  1. 1. Morphological and Behavioural Differentiation in a Pipefish

    Författare :Sarah Robinson-Wolrath; Anders Berglund; Mats Björklund; Felicity Huntingford; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; population differentiation; phenotypic plasticity; mate choice; pipefish; video playback; Biologi; Biology; Biologi;

    Sammanfattning : A central goal of evolutionary biology is to understand the processes responsible for morphological, genetic and behavioural differentiation between sexes and among geographically distinct populations. Perhaps the most significant processes are genetic drift, natural selection, phenotypic plasticity and sexual selection. LÄS MER

  3. 2. Towards Optimal Quality of Experience via Scalable Video Coding

    Författare :Pengpeng Ni; Damir Isovic; Mats Björkman; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quality-of-Experience; advanced video coding; MPEG-4; H264 AVC; Computer science; Datavetenskap; Computer Science; datavetenskap;

    Sammanfattning : To provide universal multimedia experience, multimedia streaming services need to transparently handle the variation and heterogeneity in operating environment. From the standpoint of streaming application, video adaptation techniques are intended to cope with the environmental variations by utilizing manipulations of the video content itself. LÄS MER

  4. 3. Audio-video synthesis methods for improving performance of biometric systems

    Författare :Dereje Teferi Lemma; Josef Bigun; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biometrics; Audio-Video synthesis; Image segmentation; XM2VTS; DXM2VTS; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : System security is important for any automation. It is even more so in the case of biometric systems due to the sensitive nature of the data it uses for enrollment and authentication - the subjects physical or biological trait. LÄS MER

  5. 4. On the Quality of Delivery for Variable Bit Rate Video

    Författare :Karel De Vogeleer; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Several factors affect the perceived quality of a video streamed over a network. Technical aspects related to the codec and the video play an important role besides the delivery of the video content in a timely and error-free manner. LÄS MER

  7. 5. Supporting human interpretation and analysis of activity captured through overhead video

    Författare :Mario Romero; Gregory Abowd; Georgia Institute of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ubiquitous computing; Information visualization; Computer vision; User studies; Human-computer interaction; Interactive art; Performance art; Human-computer Interaction; Människa-datorinteraktion;

    Sammanfattning : Many disciplines spend considerable resources studying behavior. Tools range from pen-and-paper observation to biometric sensing. A tool's appropriateness depends on the goal and justification of the study, the observable context and feature set of target behaviors, the observers' resources, and the subjects' tolerance to intrusiveness.
