  • Title: Quaternionic Fourier Transforms in Colour Image Analysis

  • Abstract:

    The Fourier Transform is a central and powerful tool in signal processing as well as being essential to Complex Analysis. However, it is limited to acting on complex-valued functions and thus cannot be applied directly to colour images (which have 3 real values worth of output). In this talk, I discuss the limitations of current methods then discuss several methods of extending the Fourier Transform to larger algebras (specifically the Quaternions and Clifford algebras). This informs a research plan involving the study and computer implementation of a particular Clifford Fourier Transform.
