    • Collusion resistant fingerprinting 

      Juneja, Sandeep (Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
      Digital watermarking is used to carry information by embedding information into the cover data in a perceptually visible or non visible manner. In today's sea of digital information, there are many problems associated ...

    • Content-based image retrieval system for multi-object images using a combination of features 

      Katare, Aradhana (Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
      Content-based image retrieval (CBIR) is a research area dedicated to address the retrieval of images based on automatically derived features from the content of the images in database. Traditional CBIR systems generally ...

    • Image ranking based on clustering 

      Sharma, Monika (Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
      In a typical content-based image retrieval (CBIR) system, query results are a set of images sorted by feature similarities with respect to the query. However, images with high feature similarities to the query may be very ...

    • 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 ...

    • Object segmentation in still camera videos 

      Pandya, Sweta A. (Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
      The goal of object segmentation is to simplify and change the representation of an image into more meaningful so that it can easily analyse. Segmentation is the process of partitioning the digital image into multiple ...

    • 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. ...
