finds a set of matching interest points in and and returns their pixel coordinates.
- ImageCorrespondingPoints uses ImageKeypoints to find candidate corresponding points.
- ImageCorrespondingPoints[image1,image2] returns an expression of the form , where the are lists of pixel coordinates representing the matching points in .
- The following options can be specified:
KeypointStrength 0 minimum strength of the keypoints Masking All region of interest MaxFeatures All maximum number of keypoints TransformationClass None geometrical relation between points
- With the setting Masking->roi, the set of points is restricted so that the returned points of all lie within the region of interest.
- With the settting MaxFeatures->n, at most n corresponding points with largest average keypoint strength are returned.
- Possible settings for TransformationClass include:
None no geometric constraints "Translation" translation only "Rigid" translation and rotation "Similarity" translation, rotation, and scaling "Affine" linear transformation and translation "Perspective" linear fractional transformation "Epipolar" epipolar transformation, mapping a point in one image to a line in the other image
