extract(self, image, keypoints, scales, orientations)
Note that the keypoints must be extracted using the same downscale
and :None:None:`n_scales` parameters. Additionally, if you want to extract both keypoints and descriptors you should use the faster detect_and_extract
.
Input image.
Keypoint coordinates as (row, col)
.
Corresponding scales.
Corresponding orientations in radians.
Extract rBRIEF binary descriptors for given keypoints in image.
The following pages refer to to this document either explicitly or contain code examples using this.
skimage.feature.orb.ORB.detect_and_extract
Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
