  1. 1. Spatio-Temporal Pre-Processing Methods for Region-of-Interest Video Coding

    Författare :Linda S. Karlsson; Tingting Zhang; Mårten Sjöström; Youzhi Xu; Apostolos Georgakis; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Region-of-interest; video coding; pre-processing; spatio-temporal filters; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : In video transmission at low bit rates the challenge is to compress the video with a minimal reduction of the percieved quality. The compression can be adapted to knowledge of which regions in the video sequence are of most interest to the viewer. LÄS MER

  4. 3. Development, analysis and implementation of pre-processing video filters

    Författare :Håkan Norell; Mattias O´Nils; Danny Crookes; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : The usage of video systems in households and industry has increased rapidly over the past few years. The benefits of visual processing, control and inspection have offered great opportunities for real-time video processing systems (RTVPS) for the general public as well as for heavy industries.

  5. 4. Normalization and analysis of high-dimensional genomics data

    Författare :Mattias Landfors; Patrik Rydén; Rebecka Jörnsten; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; normalization; pre-processing; microarray; downstream analysis; evaluation; sensitivity; bias; genomics data; gene expression; spike-in data; ChIP-chip; Mathematical Statistics; matematisk statistik;

    Sammanfattning : In the middle of the 1990’s the microarray technology was introduced. The technology allowed for genome wide analysis of gene expression in one experiment. Since its introduction similar high through-put methods have been developed in other fields of molecular biology. LÄS MER

  7. 5. Essays on spatial point processes and bioinformatics
