  • Picture processing techniques 
    Mergen, Tijen. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1984., 1984.)
    Image processing techniques find applications in many areas, chief among which are image enhancement, picture compression, pattern recognition, efficient picture coding and image understanding. In this master thesis, some ...
  • Probabilistic time series classification 
    Sübakan, Yusuf Cem. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    In this thesis, we investigate probabilistic methods for time series classification and clustering problems. For various classification and clustering tasks, we survey different time series models such as Markov models, ...
  • Prosodically guided syllable based speaker independent isolated Turkish word recognizer 
    Ersoy, Cem. (Thesis (M.S.)- Bogazici University. Institute for Graduate Studies in Science and Engineering, 1986., 1986.)
  • Real time speech synthesis using reflection coefficients 
    Özbek, Hüsnü. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1986., 1986)
    This master thesis gives a way to analyze speech wavefore in order to store the speech at a lower bit rate ratner than the classical ways. During the analysis Linear Predictive Coding is used where speech is represented ...
  • Robust facial feature localization in frontal views 
    Çeliktutan, Oya. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    In this thesis, we focus on the reliable detection of facial fiducial points in frontal face images, such as eye, eyebrow and mouth corners. The proposed algorithm aims to improve automatic landmarking performance in ...
  • Robust watermarking of compressive sensed measurements under noise attacks 
    Yamaç, Mehmet. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2014., 2014.)
    Traditional methods in data acquisition follow Shannon /Nyquist sampling theorem; one must sample a band-limited signal by at least two times faster than the signal bandwidth to exactly reconstruct the signal. However, ...
  • Semianalytic computer simulation of digital communication systems 
    Altınkaya, Mustafa Aziz. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1990., 1990.)
    Digital communication systems are subject to various realization imperfections and outer disturbances. The effect of such problems on the systems performance are difficult to solve using only analytical techniques. So, ...
  • Smoothing and refinement of motion vector fields for video frame rate conversion applications 
    Malkoç, Ümit. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    The main goal of Video Enhancement (VE) applications is to improve the visual quality of the video by modifying the input frame sequence. The enhancement operations could be performed in the spatial domain (each frame of ...
  • Speech synthesis using reflection coefficients 
    Bicioğlu, Önder. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1985., 1985.)
    This study outlines a method for transmitting speech using a relatively low bit rate, in comparison to traditional methods. The method is based on the theory of linear Prediction. In this approach speech is represented by ...
  • Structured and sequential representations for human action recognition 
    Çeliktutan, Oya. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    Human action recognition problem is one of the most challenging problems in the computer vision domain, and plays an emerging role in various elds of study. In this thesis, we investigate structured and sequential ...
  • Use of prosody in speech recognition 
    Akarun, Lale. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1986., 1986.)
    Automatic speech recognizers which were once considered as "a dream of mad scientists" have shown considerable success in the last decade. What has made this success possible has been the use of sophisticated mathematical ...
