`skimage.feature.orb:ORB.extract`

source: /dev/scikit-image/src/skimage/feature/orb.py :239

Signature

def extract ( self , image , keypoints , scales , orientations )

Summary

Extract rBRIEF binary descriptors for given keypoints in image.

Extended Summary

Note that the keypoints must be extracted using the same downscale and n_scales parameters. Additionally, if you want to extract both keypoints and descriptors you should use the faster detect_and_extract.

Parameters

image : ndarray of shape (K, L): Input image.
keypoints : ndarray of shape (N, 2): Keypoint coordinates as (row, col).
scales : ndarray of shape (N,): Corresponding scales.
orientations : ndarray of shape (N,): Corresponding orientations in radians.
