Logical Operators

 

The Logical operators consider the logical state for every voxel in an image as ``TRUE'' unless it is exactly equal to zero and thus is considered ``FALSE''. As discussed in Section 15.1.1 the result image is dependent on the Out operand. There are 2 operators in the Logical category as follows:

{ } xxxxx


AND
Performs a logical ``AND'' operation between corresponding pixels from the two 3D image volumes at the offsets specified in the Src1 and Src2 operands (i.e. ).

OR
Performs a logical ``OR'' operation between corresponding pixels from the two 3D image volumes at the offsets specified in the Src1 and Src2 operands (i.e. ).
