OR P - ORientation search - not Power of two

(8/22/97)

PURPOSE

Determines rotational orientation between two images. Image dimensions do not have to be powers of two.

SEE ALSO

OR [Orientation search - half circle used]
OR 3A [Orientation search - 3D, arbitrary center]
OR 3Q [Orientation search - 3D, Eulerian angles]
OR F [Orientation search - full circle used]
OR FM [Orientation search - full circle used, find > one peak]
OR M [Orientation search - find > one peak]

USAGE

.OPERATION: OR P,X10,X11

[The optional output parameters X10,X11 specify register positions for the rotation angle and the value of the angular correlation peak found in this operation.]

.INPUT FILE: UUU001
[Enter name of the file.]

.REFERENCE FILE: GGG002
[Enter the name of the file containing the reference picture; dimensions must correspond to those of the first picture.]

.FIRST AND LAST RING: 5,15
[Only rings with the radii in the range 5-15 (in pixel units) will be used.]

.SKIP: 1
[If skip=0 or 1 then each ring between 5 and 15 will be taken; for skip=2 every second, and so on.]

NOTES

  1. Images do not have to have power-of-two dimensions.
