Abstract
A system and method for detecting and representing a directionality of objects in an image. A system and method may process an input image to produce a set of direction-filtered images, calculate a local gradient field based on the of direction-filtered images, calculate a magnitude of a projection of a local gradient on a predefined direction and use the projection to represent a directionality of the set of objects. A system and method may calculate a local orientation angle and associate the local orientation angle with pixels in an input digital image.
