    • Classification of 3D volume data using finite mixture models 

      Phophalia, Ashish (Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
      The 3D imaging provides better view of objects from three directions as compared to 2D imaging where front face of object can be viewed only. It involves a complex relationship as compared to 2D imaging and hence computationally ...

    • Depth from defocus 

      Khatri, Nilay (Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
      With the recent innovations in 3D technology accurate estimation of depth is very fascinating and challenging problem. In this thesis, a depth estimation algorithm, utilizing Singular Value Decomposition to compute orthogonal ...

    • Disparity estimation by stereo using particle swarm optimization and graph cuts 

      Nahar, Sonam (Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
      Stereo vision is based on the process of obtaining the disparity from a left and a right view of a scene. By obtaining the disparity, we find the distance (depth) of each object point from the camera so that we can construct ...

    • Practical approach for depth estimation and image restoration using defocus cue 

      Ranipa, Keyur R. (Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
      Reconstruction of depth from 2D images is an important research issue in computer vision. Depth from defocus (DFD) technique uses space varying blurring of an image as a cue in reconstructing the 3D structure of a scene. ...
