  2. 1. Face Recognition : A Single View Based HMM Approach

    Author : Hung Son Le; Haibo Li; Josef Bigun; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; face recognition; pattern recognition; computer vision; HMM; Hidden Markov Models; contrast enhancement; pyramid fusion; image processing; Computer science; Datavetenskap;

    Abstract : This dissertation addresses the challenges of giving computers the ability of doing face recognition, i.e. discriminate between different faces. Face recognition systems are commonly trained with a database of face images, becoming “familiar” with the given faces. READ MORE

  4. 2. Information state based speech recognition

    Author : Rebecca Jonson; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; dialogue systems; speech recognition; language modelling; dialogue move; dialogue context; ASR; higher level knowledge; linguistic knowledge; N-Best re-ranking; confidence scoring; confidence annotation; information state; ISU approach;

    Abstract : One of the pitfalls in spoken dialogue systems is the brittleness of automatic speech recognition (ASR). ASR systems often misrecognize user input and they are unreliable when it comes to judging their own performance. READ MORE

  5. 3. Controlling the Swedish state : Studies on formal and informal bodies of control

    Author : Isabel Schoultz; Tove Pettersson; Åström Karsten; Penny Green; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Parliamentary Ombudsman; Chancellor of Justice; United Nations; European Court of Human Rights; NGOs; control of the state; accountability; state crime; Sweden; techniques of neutralizations; problem representations; immigration; kriminologi; Criminology;

    Abstract : The dissertation aims to develop an understanding of the outcomes and limitations of formal and informal control of the Swedish state, and of the positions and strategies of the social agents involved in this field. The dissertation contributes with new perspectives on controls directed at the state, comparing various control organs (the Parliamentary Ombudsman, the Chancellor of Justice, the United Nations, the European Court of Human Rights and NGOs) and focusing on a wide range of wrongs and harms by the Swedish state.

  6. 4. Molecular recognition in the solid state : crystal structure studies of selected inclusion compounds of host molecules with roof-shaped skeleton

    Author : Olga Helmle; Janusz Lipkowski; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; strukturkemi; Structural Chemistry;

    Abstract : This survey presents the results of single-crystal X-ray diffraction investigations of nine selected organic heteromolecular complexes in terms of the molecular recognition concept. The host molecules of the studied inclusion compounds have the 9,10-dihydro-9,10-ethanoanthracene moiety in common, to which various sensor groups possessing both proton donor and acceptor abilities are attached.

  7. 5. Efficient Methods for Automatic Speech Recognition

    Author : Alexander Seward; KTH; []
    Keywords : speech recognition; algorithms; hidden markov models; HMM; weigted finite-state transducers;

    Abstract : This thesis presents work in the area of automatic speech recognition (ASR). The thesis focuses on methods for increasing the efficiency of speech recognition systems and on techniques for efficient representation of different types of knowledge in the decoding process. READ MORE
