Variant 1:
Positional Arguments
images:

.Image set.
Return
keypoints:
[vector_KeyPoint]
.Input collection of keypoints. Keypoints for which a descriptor cannot be computed are removed. Sometimes new keypoints can be added, for example: SIFT duplicates keypoint with several dominant orientations (for each orientation).
descriptors:
