  1. 21. Image segmentation using snakes and stochastic watershed : with applications to microscopy images of biological tissue

    Författare :Bettina Selig; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The purpose of computerized image analysis is to extract meaningful information from digital images. To be able to find interesting regions or objects in the image, first, the image needs to be segmented. This thesis concentrates on two concepts that are used for image segmentation: the snake and the stochastic watershed. LÄS MER

  3. 22. On Virtual Surgical Planning in Cranio-Maxillofacial Surgery

    Författare :Johanna Nilsson; Andreas Thor; Risto Kontio; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Virtual surgical planning. Computer assisted planning. 3D computer model. Orbital segmentation. Craniomaxillofacial surgery planning. Haptics.; Oral and Maxillofacial Surgery; Käkkirurgi;

    Sammanfattning : The complex three-dimensional (3D) anatomy of the cranio-maxillofacial (CMF) region makes surgery a challenging task. Virtual surgical planning (VSP) has the potential to increase accuracy, reproducibility and shorten operation time. LÄS MER

  4. 23. Discriminative correlation filters in robot vision

    Författare :Andreas Robinson; Michael Felsberg; Per-Erik Forssén; Fahad Khan; Didier Stricker; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In less than ten years, deep neural networks have evolved into all-encompassing tools in multiple areas of science and engineering, due to their almost unreasonable effectiveness in modeling complex real-world relationships. In computer vision in particular, they have taken tasks such as object recognition, that were previously considered very difficult, and transformed them into everyday practical tools. LÄS MER

  5. 24. Semantic mapping using virtual sensors and fusion of aerial images with sensor data from a ground vehicle

    Författare :Martin Persson; Achim Lilienthal; Javier González; Örebro universitet; []
    Nyckelord :semantic mapping; aerial image; mobile robot; supervised learning; semi-supervised learning; TECHNOLOGY; TEKNIKVETENSKAP; Industriell mätteknik; Industrial Measurement Technology;

    Sammanfattning : In this thesis, semantic mapping is understood to be the process of putting a tag or label on objects or regions in a map. This label should be interpretable by and have a meaning for a human. The use of semantic information has several application areas in mobile robotics. LÄS MER

  7. 25. Algorithms for aggregate information extraction from sequences

    Författare :Fredrik Bengtsson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Sammanfattning : In this thesis, we propose efficient algorithms for aggregate information extraction from sequences and multidimensional arrays. The algorithms proposed are applicable in several important areas, including large databases and DNA sequence segmentation. LÄS MER
