  2. 11. Lip-motion biometrics for audio-visual identity recognition

    Author : Maycel Isaac Faraj; Massimo Tistarelli; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biometrics; Lip motion; Audio-visual signals; Speech recognition; Speaker recognition; Digit recognition; Image analysis; Bildanalys;

    Abstract : Biometric recognition systems have been established as powerful security tools to prevent unknown users from entering high risk systems and areas. They are increasingly being utilized in surveillance and access management (city centers, banks, etc.) by using individuals' physical or biological characteristics. READ MORE

  4. 12. Robust Estimation of Motion Parameters and Scene Geometry : Minimal Solvers and Convexification of Regularisers for Low-Rank Approximation

    Author : Marcus Valtonen Örnhag; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; Visual Odometry; Simultaneous Localization and Mapping; minimal solvers; Convex relaxations; Structure from motion;

    Abstract : In the dawning age of autonomous driving, accurate and robust tracking of vehicles is a quintessential part. This is inextricably linked with the problem of Simultaneous Localisation and Mapping (SLAM), in which one tries to determine the position of a vehicle relative to its surroundings without prior knowledge of them.

  5. 13. Computer Vision: From Motion Capture to Tabletop Interaction

    Author : Tommaso Piazza; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optical tracking; tabletop; motion capture; cscw; missing maker; multi-touch;

    Abstract : This thesis presents the work done by the candidate in the domain of Human-Computer Interaction. In particular, the candidate has investigated how techniques in Computer Vision can be used to enable new forms of interaction. The work investigates areas such as motion capture and multi-user, multi-touch interaction for tabletop systems. READ MORE

  6. 14. Natural Vision for Artificial Systems, Active Vision and Thought

    Author : Lars Kopp; Kognitiv semiotik; []
    Keywords : HUMANIORA; HUMANITIES; visual alphabet; representations; robotics; language; artificial vision; cognition; Artificial intelligens; Artificiell intelligens;

    Abstract : The visual system in animals and humans consists of a number of information processing units that are here called visual routines. These routines are specialized in handling different cognitive tasks, for example, object recognition, motion, stereo, color, texture, and optic flow. READ MORE

  7. 15. Vision Beyond the Fovea: Evaluation and Stimuli Properties

    Author : Abinaya Priya Venkataraman; Linda Lundström; Hema Radhakrishnan; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Peripheral vision; Visual optics; Optical correction; Orientation; Stimulus extent; Moving stimulus; Contrast sensitivity; Visual acuity; Central vision loss; Myopia; Biological Physics; Biologisk fysik;

    Abstract : This research is about evaluating vision in the periphery. Peripheral vision is of fundamental importance in the performance of our everyday activities. The aim of this thesis is to develop methods suitable for the evaluation of peripheral vision and to assess how different visual functions vary across the visual field. READ MORE
