Struct cv_core::KeyPoint [−][src]
Expand description
A point on an image frame. This type should be used when the point location is on the image frame in pixel coordinates. This means the keypoint is neither undistorted nor normalized.
For calibrated coordinates, use a type that implements Bearing.
This can be a type from a camera model crate (like cv-pinhole), or
it can be the Unit<Vector3<f64>> type, which implements bearing.

The inverse inclusion map: attempts to construct self from the equivalent element of its
superset. Read more
Checks if self is actually part of its subset T (and can be converted to it).
Use with care! Same as self.to_subset but without any property checks. Always succeeds.
