ImageCorrespondingPoints

ImageCorrespondingPoints[image1, image2]
finds a set of matching interest points in and and returns their pixel coordinates.

Details and OptionsDetails and Options

  • 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 .
  • ImageCorrespondingPoints by default imposes no geometric relation between the matching point sets.
  • The geometric relation between the matching points can be constrained by setting the option. The default setting is "Transformation"->None. Possible settings include:
  • "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
    Noneno geometric constraints
  • With the setting Masking->roi, the set of points is restricted so that the returned points of all lie within the region of interest.
