vpi.PyramidalKeypointF32

class vpi.PyramidalKeypointF32

Define a pyramidal keypoint with float32 coordinates.

The coordinate includes the (x, y) position in an image inside a pyramid, and (octave and layer) selects a specific image on that pyramid. Pyramids are used to approximate the scale space with one or more resolution levels, called octaves, where in each octave there is one or more smoothing layers.
