  2. 21. Dependability of IT Systems in Emergency Situations – Theory and Practice

    Author : Kim Weyns; Institutionen för datavetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dependability; IT Systems; Emergency Management; Markov Models; Sensitivity Analysis; Swedish Municipalities;

    Abstract : As our dependence on IT systems increases, evaluating the dependability of critical IT systems becomes more important. One of the main challenges in software reliability engineering is the sensitivity of software systems to a changing usage. READ MORE

  6. 24. Channel-Coded Feature Maps for Computer Vision and Machine Learning

    Author : Erik Jonsson; Michael Felsberg; Florentin Wörgötter; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; computer vision; machine learning; object recognition; pose estimation; Image analysis; Bildanalys;

    Abstract : This thesis is about channel-coded feature maps applied in view-based object recognition, tracking, and machine learning. A channel-coded feature map is a soft histogram of joint spatial pixel positions and image feature values. Typical useful features include local orientation and color. READ MORE

  7. 25. Lip-motion and speech biometrics in person recognition

    Author : Maycel Isaac Faraj; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Audio-visual recognition; biometrics; Biometric recognition; Speaker verification; Speaker authentication; Person identification; Lip movements; Motion; Structure tensor; Orientation; Optical flow; Hidden Markov Model; Gaussian Markov Model; Lip-motion; Image analysis; Bildanalys;

    Abstract : Biometric identification techniques are frequently used to improve security, e.g. in financial transactions, computer networks and secure critical locations. The purpose of biometric authentication systems is to verify an individual by her biological characteristics including those generating characterisitic behaviour. READ MORE
