  1. 16. Activity recognition in resource-constrained pervasive systems

    Författare :Niklas Karvonen; Chris Nugent; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pervasive Mobile Computing; Distribuerade datorsystem;

    Sammanfattning : There is an increasing need for personalised and context-aware services in our everyday lives and we rely on mobile and wearable devices to provide such services. Data collected from these devices includes important information about users’ movements, locations, physiological status, and environment. LÄS MER

  3. 17. Mining Speech Sounds : Machine Learning Methods for Automatic Speech Recognition and Analysis

    Författare :Giampiero Salvi; Björn Granström; Torbjørn Svendsen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; speech; machine learning; data mining; signal processing; Computer science; Datavetenskap;

    Sammanfattning : This thesis collects studies on machine learning methods applied to speech technology and speech research problems. The six research papers included in this thesis are organised in three main areas. The first group of studies were carried out within the European project Synface. LÄS MER

  4. 18. Recognition and Evaluation by Video Synthesis Methods and Symmetry Features

    Författare :Dereje Teferi Lemma; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Biometrics; eye detection; video synthesis; liveness detection; camera calibration; damascening; Generalized Structure Tensor; symmetry codes;

    Sammanfattning : Biometrics is being increasingly utilized for person authentication. It requires little or no efforts from the user as compared to traditional non-biometric systems where the user has to memorize PIN codes and passwords or carry pass cards and keys that can be easily forgotten or lost.

  5. 19. Anonymizing Faces without Destroying Information

    Författare :Felix Rosberg; Cristofer Englund; Eren Aksoy; Fernando Alonso-Fernandez; Vitomir Struc; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anonymization; Data Privacy; Generative AI; Reconstruction Attacks; Deep Fakes; Facial Recognition; Identity Tracking; Biometrics;

    Sammanfattning : Anonymization is a broad term. Meaning that personal data, or rather data that identifies a person, is redacted or obscured. In the context of video and image data, the most palpable information is the face. Faces barely change compared to other aspect of a person, such as cloths, and we as people already have a strong sense of recognizing faces. LÄS MER

  7. 20. Auditory and Olfactory Abilities in Blind and Sighted Individuals : More Similarities than Differences

    Författare :Stina Cornell Kärnekull; Maria Larsson; Mats E Nilsson; Johan Willander; Fredrik U Jönsson; Johannes Frasnelli; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; absolute threshold; audition; autobiographical memory; blindness; discrimination; episodic recognition; identification; imagery; judgments of learning; memory; metacognition; olfaction; onset age of blindness; reminiscence bump; sensory compensation; Psychology; psykologi;

    Sammanfattning : Blind individuals face various challenges in everyday life because of the lack of visual input. However, since they need to rely on the non-visual senses for everyday tasks, for instance, when navigating the environment, the question has been raised as to whether perceptual and cognitive abilities in these senses may be enhanced.
