  2. 1. 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

  4. 2. 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

  5. 3. The perception of actions and interactions : And the importance of context

    Author : Joshua Juvrud; Gustaf Gredebäck; Denis Mareschal; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; action understanding; action perception; motion; perception; context; environment; eye-tracking; pupil dilation; Psychology; Psykologi;

    Abstract : The perception of actions and interactions is a dynamic process linked with perceptual processes, the internal and external states of the individual, prior experiences, and the immediate environment. Given these differential contexts, it is very likely there are differences in how infants perceive, interpret, and respond to actions. READ MORE

    Abstract : Maya Deren’s corpus of work, which has been given various designations within the American avant-garde filmmaking practice of the 1940’s and 1950’s, will be analysed according to the biographical legend—an approach that focuses on authorship within the historical conditions of conception and reception. Influences on her theories in art and ethnography will be noted through several historical discourses: the French Symbolist Poets, Henri Bergson, Kurt Koffka, T. READ MORE

  7. 5. Human Motion Analysis for Creating Immersive Experiences

    Author : Farid Abedan Kondori; Haibo Li; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : From an early age, people display the ability to quickly and effortlessly interpret the orientation and movement of human body parts, thereby allowing one to infer the intentions of others who are nearby and to comprehend an important nonverbal form of communication. The ease with which one accomplishes this task belies the difficulty of a problem that has challenged computational systems for decades, human motion analysis. READ MORE
