  1. 1. 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

    Sammanfattning : The evolution of advanced radio transmission technologies for third and future generation mobile radio systems has paved the way for the delivery of mobile multimedia services. This is further enabled through contemporary video coding standards, such as H. LÄS MER

  4. 3. Investigating Communicative Feedback Phenomena across Languages and Modalities

    Författare :Loredana Sundberg Cerrato; David House; Marianne Gullberg; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; Linguistics; Lingvistik;

    Sammanfattning : This thesis deals with human communicative behaviour related to feedback, analysed across languages (Italian and Swedish), modalities (auditory versus visual) and different communicative situations (human-human versus human-machine dialogues). The aim of this study is to give more insight into how humans use communicative behaviour related to feedback and at the same time to suggest a method to collect valuable data that can be useful to control facial and head movements related to visual feedback in synthetic conversational agents.

  5. 4. The value of new sonographic modalities, demographic, biometric and proliferative variables for the risk prediction in endometrial cancer

    Författare :Rasmus W Green; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Endometrial cancer is the sixth most common type of cancer among women worldwide and constitutes 4.8% of all cancer in women. The incidence is highest in highincome countries, given how age and obesity are the two most important risk factors. The majority of cases present at an early stage, with a favourable prognosis.

  7. 5. Study and implementation of stereo vision systems for robotic applications

    Författare :Lazaros Nalpantidis; Antonios Gasteratos; Greece Democritus University of Thrace Production and Management Engineering Dept.; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Stereo vision has been chosen by natural selection as the most common way to estimate the depth of objects. A pair of two-dimensional images is enough in order to retrieve the third dimension of the scene under observation. The importance of this method is great, apart from the living creatures, for sophisticated machine systems, as well. LÄS MER
