Name: WlzCrossCorValue - computes the cross correlation value of two objects.

Synopsis

WlzCrossCorValue [-h] [-n] [-o<out obj>] [-u] [<in obj 0>] [<in obj 1>]

Options

-h	Help, prints usage message.
-n	Normalise the cross-correlation value by dividing it by the area/volume over which it is computed.
-o	Output file for the cross-correlation value.
-u	Compute the cross-correlation value within the union of objects domains. The default is to compute the cross correlation value within the intersection of the objects domains.

Description: Computes the cross correlation value (with zero shift) of two 2D spatial domain objects with grey values. The input objects are read from stdin and values are written to stdout unless the filenames are given.

Examples

WlzCrossCorValue -o out.num in0.wlz in1.wlz

The cross correlation value computed from the objects read from in0.wlz and in1.wlz is written to the file out.num.
