Directional and omnidirectional edge enhancement based on radial Hilbert transform of Gabor filter
A directional and omnidirectional edge enhancement method is proposed based on radial Hilbert transform (RHLT) of directional Gabor filter (DGF). A new transfer function is introduced to develop a new RHLT that can be rotated to enhance edges along the specified direction. Furthermore, to increase t...
