Abstract :
We examine the performance of phase-based and energy-based techniques for estimating image orientation, emphasizing measurement stability under deformations that commonly occur in natural images. We also present a new energy-based technique for estimating multiple orientations in a neighbourhood and for reliably extracting multiple orientations from textured image regions
