Struct opencv::xfeatures2d::AffineFeature2D

pub struct AffineFeature2D { /* private fields */ }

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_KeyPoint “Elliptic_KeyPoints” instead of [KeyPoint] “KeyPoints”.
