Abstract :
A novel two-dimensional (2D) filtering operation, involving both curl and divergence, is applied to the 2D Clifford Fourier transform (CFT) in order to simultaneously enhance important features of a 2D vector field, such as vortices and pairs of sources and sinks. Applications are envisaged for enhancing vector field images in such sampled vector field images as fluid flow, gas flow and biomedical image processing.
