Class implementing affine adaptation for key points.
A FeatureDetector and a DescriptorExtractor are wrapped to augment the detected points with their affine invariant elliptic region and to compute the feature descriptors on the regions after warping them into circles.
The interface is equivalent to Feature2D, adding operations for Elliptic_KeyPoints instead of KeyPoints.
