    • Active contours in action 

      Shah, Pratik P. (Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
      There was considerable success in converting images into something like line drawings without resorting to any but the most general prior knowledge about smoothness and continuity. That led to the problem of “grouping” ...

    • Fractal based approach for image segmentation 

      Londhe, Tushar (Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
      In this thesis, we have proposed an algorithm for image segmentation, using the fractal codes. The basic idea behind this algorithm is to use fractal codes for the image segmentation. This method uses compressed codes ...

    • New learning based super resolution using contourlet transform 

      Singh, Vineet P. (Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
      new learning based super-resolution reconstruction using contourlet transforms is proposed. contourlet transform provides high degree of directionality. It captures geometrical smoothness along multiple directions and ...

    • 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. ...

    • Practical approaches for photometric stereo 

      Sharma, Swati (Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
      In this thesis work, we aim to propose approaches for photometric stereo that are less time consuming and have low computational requirements. Many applications of computer vision require high resolution 3-D structure of ...

    • Super-resolution of hyperspectral images 

      Bhimani, Amitkumar H. (Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
      Hyperspectral (HS) images are used for space areal application, target detection and remote sensing application. HS images are very rich in spectral resolution but at a cost of spatial resolution. HS images generated by ...

    • Variants of orthogonal neighborhood preserving projections for image recognition 

      Koringa, Purvi Amrutlal (Dhirubhai Ambani Institute of Information and Communication Technology, 2018)
      With the increase in the resolution of image capturing sensors and data storagecapacity, a huge increase in image data is seen in past decades. This informationupsurge has created a huge challenge for machines to perform ...
