    • FPGA implementation of image compression algorithm using wavelet transform 

      Rawat, Nitin (Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
      This work presents FPGA implementation of image compression algorithm by using wavelet transform. Here the emphasis has been made on algorithmic encoding, the first step of image compression problem. The transform that has ...

    • 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 ...

    • On wavelets and fractal modulation 

      Mehta, Shalin (Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
      The thesis considers a communication problem - that of communicating over a channel having simultaneously unknown bandwidth and unknown duration. As a solution to this problem, the thesis looks into a modulation scheme - ...

    • Video compression using color transfer based on motion estimation 

      Reddy, Pandu Ranga M. (Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
      Many compression techniques were developed in last decade and are being used in many applications like HDTV, Videoconferencing, Videophone, multimedia work stations and mobile image communications. It is also certain that ...
