  • Exact Unbiased Inverse of the Anscombe Transformation and its Poisson-Gaussian Generalization 
    Mäkitalo, Markku (2013-03-01)
    Digital image acquisition is an intricate process, which is subject to various errors. Some of these errors are signal-dependent, whereas others are signal-independent. In particular, photon emission and sensing are ...
  • Light Field Synthesis from Irregularly Distributed Data Points 
    Uzunov, Vladislav (2011-10-07)
    A scalar light field is any stationary monochromatic wave in the visible spectrum which propagates in an isotropic, homogeneous, non-dispersive and non-magnetic medium and thus obeys the Helmholtz wave equation. This thesis ...
  • Mapping Techniques for Voice Conversion 
    Helander, Elina (2012-06-19)
    Speaker identity plays an important role in human communication. In addition to the linguistic content, speech utterances contain acoustic information of the speaker characteristics. This thesis focuses on voice conversion, ...
  • Packet-Switched Streaming Service in Non-Bitrate-Guaranteed Mobile Networks 
    Lundan, Miikka (2011-06-03)
    Streaming allows consuming content, such as video or audio, without storing it on a receiving device. The benefit of streaming is that it requires little memory from the device. The drawback is that the device must always ...
  • Perceptually Optimized Visualization on Autostereoscopic 3D Displays 
    Boev, Atanas (2012-08-31)
    The family of displays, which aims to visualize a 3D scene with realistic depth, are known as "3D displays". Due to technical limitations and design decisions, such displays create visible distortions, which are interpreted ...
  • Singing Voice Recognition for Music Information Retrieval 
    Mesaros, Annamaria (2012-09-04)
    This thesis proposes signal processing methods for analysis of singing voice audio signals, with the objectives of obtaining information about the identity and lyrics content of the singing. Two main topics are presented, ...
  • Spatial and Content-based Audio Processing using Stochastic Optimization Methods 
    Mäkinen, Toni (2013-05-21)
    Stochastic optimization (SO) represents a category of numerical optimization approaches, in which the search for the optimal solution involves randomness in a constructive manner. As shown also in this thesis, the stochastic ...
  • Statistical and Information Theoretic Approaches to Model Selection and Averaging 
    Liski, Antti (2013-04-12)
    In this thesis we consider model selection (MS) and its alternative, model averaging (MA), in seven research articles and in an introductory summary of the articles. The utilization of the minimum description length (MDL) ...
  • Switching and Oscillatory Dynamics of Genetic Networks 
    Potapov, Ilya (2013-01-18)
    Bi-stable and periodic behaviors are present in living beings. Mechanisms capable of bi-stability provide organisms with the means to choose between states, while cyclic systems can be used to track time, and thus regulate ...
  • Techniques for Spectral Voice Conversion 
    Popa, Victor (2012-06-01)
    Voice conversion is a speech technology encompassing transformations applied to the speech signal with the purpose of changing the perceived speaker identity from a source voice to a desired target voice. The principal use ...
