    • Spatial and spectral regularization in unmixing of remotely sensed data 

      Patel, Jignesh Rameshchandra (Dhirubhai Ambani Institute of Information and Communication Technology, 2021)
      The hyperspectral imaging opens the broad possibilities for remote sensing data analysis with it’s rich spectral information. However, this has a trade-off with limited spatial details due to the presence of several hardware ...

    • Spectrum sensing for cognitive radio 

      Manharlal, Captain Kamal (Dhirubhai Ambani Institute of Information and Communication Technology, 2019)
      Due to the rapid growth of new wireless communication services and applications, need for radio frequency (RF) spectrum is continuously increasing. Most of the available RF spectrum is already been licensed to the existing ...

    • Techniques for denoising brain magnetic resonance images 

      Phophalia, Ashish (Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
      Advances in the computational science joined medical imaging domain to help humanity. It offers great support in clinical practices where automatic Computer Added Systems (CAD) help in identification and localization of ...

    • 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 ...

    • Vector graph representation for 3D meshes and algorithms for mesh deformation, enveloping, interpolation and morphing 

      Domadiya, Prashant Manishbhai (Dhirubhai Ambani Institute of Information and Communication Technology, 2021)
      The performance of the tools developed for graphics and animation depends on the underlying representation of the geometric model of the objects. The geometric model in turn describes the geometry of the real world object. ...

    • Voice conversion: alignment and mapping perspective 

      Shah, Nirmesh J. (Dhirubhai Ambani Institute of Information and Communication Technology, 2019)
      Understanding how a particular speaker is producing speech, and mimicking one's voice is a difficult research problem due to the sophisticated mechanism involved in speech production. Voice Conversion (VC) is a technique ...

    • Wavelets and filter banks: novel approaches for real and complex-valued transform designs 

      Sharad, Gajbhar Shrishail (Dhirubhai Ambani Institute of Information and Communication Technology, 2017)
      Processing of natural images stored as 2-D discrete signals is an inevitable task in almost all areas of image processing. In order to have the desired processing results, directional image representation can be considered ...
