KeypointStrength

is an option for ImageKeypoints and related functions to specify a minimum strength of detected keypoints.

Details

Using KeypointStrength->s, all returned keypoints have strengths greater than or equal to s.
KeypointStrength->0 can be used to remove any strength constraint.

Examples

By default, functions use an automatic strength threshold:

Wolfram Language code:

i = [image];
ImageKeypoints[i];
HighlightImage[i, {PointSize@Medium, %}]

Wolfram Language code:

ImageKeypoints[i, KeypointStrength -> .002];
HighlightImage[i, {PointSize@Medium, %}]
