ImageCorrespondingPoints

finds a set of matching interest points in

and

and returns their pixel coordinates.

ImageCorrespondingPoints uses ImageKeypoints to find candidate corresponding points.

ImageCorrespondingPoints 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 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
	None	no geometric constraints
