  • A model of active and attentive vision 
    Soyer, Çağatay. (Thesis (Ph.D.) - Bogazici University. Institute of Biomedical Engineering, 2002., 2002.)
    Biological vision systems explore their environment by allocating their resources to interesting parts of a scene, using both physical and mental attention mechanisms. The result of this active and attentive vision behavior ...
  • Asynchronous processing of luminance difference and motion in visual perception 
    İşcan, Onur. (Thesis (M.S.)-Bogazici University. Institute of Biomedical Engineering, 2008., 2008.)
    This study is related with the perception of first-order motion. The processing of visual information in the human brain is accomplished by numerous visual streams. Each stream is specialized to process different attributes ...
  • Characterization of genes involved in photoreceptor differentiation 
    Öztürk, Arzu. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2010., 2010.)
    The one receptor - one neuron rule is a common phenomenon observed in sensory organs. In the Drosophila eye, each photoreceptor expresses one of six different rhodopsin genes. The expression patterns of inner photoreceptors ...
  • Early processing of scatterplots :|the impact of outlier and content on trend-line estimation 
    Oral, Emre. (Thesis (M.A.) - Bogazici University. Institute for Graduate Studies in the Social Sciences, 2021., 2021.)
    Recently, there has been a growing interest in integrating data visualization research with basic visual perception findings. Following this line of reasoning, in this thesis, I investigated how our understanding of ensemble ...
  • Fovea based coding for video streaming 
    Dikici, Çağatay. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2004., 2004.)
    Attentive robots, inspired by human-like vision - are required to have visual systems with fovea-periphery distinction and saccadic motion capability. Thus, each frame in the incoming image sequence has nonuniform sampling ...
  • Nonlinear dimensionality reduction methods for pattern recognition 
    Turhan, Burak. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2004., 2004.)
    The aim of dimensionality reduction is to find a lower dimensional, simpler representation while keeping the important information in the data. It is essential to employ dimensionality reduction for high dimensional data ...
  • Supra-threshold contrast perception in glaucomatous and normal human subjects 
    Utine, Canan Aslı. (Thesis (M.S.)-Bogazici University. Institute of Biomedical Engineering, 2006., 2006.)
    The lateral inhibition mechanism of the sensorineural retina provides our visual systemwith a mean to sharpen the boundary between different luminances. Contrast is defined as the ratioof the difference in the luminance ...
  • The immediate object of visual perception 
    Uluç, Işıl. (Thesis (M.A.)-Bogazici University. Institute for Graduate Studies in the Social Sciences, 2007., 2007.)
    This thesis aims to understand the nature of the visual perception by mainly focusing on the question, “What is the immediate object of visual experience?” To this aim, I will examine the theories of perception and give ...
