RESEARCH INTERESTS

For almost last three years I have been working as post-doc in University of Adelaide, Australia and During my PhD, I was mainly focused on developing sophisticated prior models for images and videos. In the high-level sense, we have incorporated the informations that distinguish a realistic image from any 2D random matrices. The title of my thesis is "Efficient priors for Multi-frame and Single-frame Super Resolution" and my supervisor was Prof. Bhabatosh Chanda.

My research interests primarily lie in the following

  • 3D multi-view geometry
  • image processing
  • computer vision
  • machine learning
  • document processing
  • video analysis

NEWS
