Struct opencv::xfeatures2d::AffineFeature2D
source · pub struct AffineFeature2D { /* private fields */ }
Expand description
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”.

unsafe fn modify_inplace<Res>( &mut self, f: impl FnOnce(&Mat, &mut Mat) -> Res ) -> Res
Helper function to call OpenCV functions that allow in-place modification of a
Mat
or another similar object. By passing
a mutable reference to the Mat
to this function your closure will get called with the read reference and a write references
to the same Mat
. This is of course unsafe as it breaks the Rust aliasing rules, but it might be useful for some performance
sensitive operations. One example of an OpenCV function that allows such in-place modification is imgproc::threshold
. Read more
