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.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
