    • Study of frames in Hilbert C?-modules and their representation as regular k-distance sets 

      Rajput, Ekta (Dhirubhai Ambani Institute of Information and Communication Technology, 2022)
      The definition of basis in the study of vector space is very antagonistic. As a resultof that, one might look for a prominent substitute. Frames are such a notion, asthe linear independence between the frame elements is ...

    • 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 ...

    • Water Footprint in the Context of Urban Water Management: Challenges and Opportunities 

      Banerjee, Alik (Dhirubhai Ambani Institute of Information and Communication Technology, 2023)
      Water, a crucial resource in preserving the ecology in good shape, has becomescarce. Water footprint (WF) measure has been proposed in the literature to understandthis prevailing water crisis. The WF, which consists of ...

    • 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 ...
