1. A method of determining an orientation of an object within an image, the method comprising:
- determining responses of at least two classifiers in at least one region of the image corresponding to the object, the classifiers having been trained to identify the given object in different specific orientations; and
determining the orientation of the object as an average of the specific orientations, weighted by the responses of their respective classifiers, excluding specific orientations of classifiers having a response smaller than zero.

Abstract
A method of determining an orientation of an object within an image. The method determines the responses of at least two classifiers in at least one region of the image corresponding to the object. The classifiers have been trained to identify a given object in different specific orientations. The orientation of the object is determined as an average of the specific orientations, weighted by the responses of their respective classifiers.

8. Apparatus for processing an image, the apparatus comprising:
-
at least one processor; and at least one memory including computer program instructions, the at least one memory and the computer program instructions being configured to, with the at least one processor, cause the apparatus to perform a method of determining an orientation of an object within an image, the method comprising; determining responses of at least two classifiers in at least one region of the image corresponding to the object, the classifiers having been trained to identify the given object in different specific orientations; and determining the orientation of the object as an average of the specific orientations, weighted by the responses of their respective classifiers, excluding specific orientations of classifiers having a response smaller than zero.

9. A non-transitory computer-readable storage medium comprising computer-executable instructions which, when executed by a processor, cause a computing device to perform a method of determining an orientation of an object within an image, the method comprising:
-
determining responses of at least two classifiers in at least one region of the image corresponding to the object, the classifiers having been trained to identify the given object in different specific orientations; and determining the orientation of the object as an average of the specific orientations, weighted by the responses of their respective classifiers, excluding specific orientations of classifiers having a response smaller than zero.
