  2. 6. Low and Medium Level Vision Using Channel Representations

    Author : Per-Erik Forssén; Gösta Granlund; Jim Little; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis introduces and explores a new type of representation for low and medium level vision operations called channel representation. The channel representation is a more general way to represent information than e.g. as numerical values, since it allows incorporation of uncertainty, and simultaneous representation of several hypotheses.

  4. 7. Parameter Estimation and Filtering Using Sparse Modeling

    Author : Ashkan Panahi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sparsity based tracking; Sparsity based techniques; off-grid effect; parameter estimation; continuous basis pursuit; compressed sensing;

    Abstract : Sparsity-based estimation techniques deal with the problem of retrieving a data vector from an undercomplete set of linear observations, when the data vector is known to have few nonzero elements with unknown positions. It is also known as the atomic decomposition problem, and has been carefully studied in the field of compressed sensing. READ MORE

  5. 8. Model Based Speech Enhancement and Coding

    Author : David Yuheng Zhao; Bastiaan Kleijn; Peter Kabal; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; statistical model; Gaussian mixture mdel GMM ; hidden Markov model HMM ; moise reduction; Telecommunication; Telekommunikation;

    Abstract : In mobile speech communication, adverse conditions, such as noisy acoustic environments and unreliable network connections, may severely degrade the intelligibility and natural- ness of the received speech quality, and increase the listening effort. This thesis focuses on countermeasures based on statistical signal processing techniques. READ MORE

  6. 9. Dynamic Optimization for Agent-Based Systems and Inverse Optimal Control

    Author : Yibei Li; Xiaoming Hu; Per Enqvist; Yishao Zhou; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inverse optimal control; formation control; differential game; credit scoring; Mathematics; Matematik;

    Abstract : This dissertation is concerned with three problems within the field of optimization for agent--based systems. Firstly, the inverse optimal control problem is investigated for the single-agent system. Given a dynamic process, the goal is to recover the quadratic cost function from the observation of optimal control sequences. READ MORE
