Detailed Description

ImageViz SoLogicalImageProcessing engine performs logical operations between two image.

SoLogicalImageProcessing performs a logical operation between an image and another image.

For an introduction to logical operations, see section Logical Operations.

Member Enumeration Documentation

enum SoLogicalImageProcessing::LogicalOperator
Enumerator:
AND 

The AND logical operator computes the logical and between two images $I_1$ and $I_2$.

On a binary image, it is equivalent to a minimum operation, or to the intersection of two sets, as it appears in the boolean table and the figure below.

\[ \begin{array}{|c|c|c|} \hline A & B & A ~ \wedge ~ B\\ \hline 1 & 1 & 1\\ 1 & 0 & 0\\ 0 & 1 & 0\\ 0 & 0 & 0\\ \hline \end{array} \]

Intersection of two images demonstrating the logical AND

OR 

The OR logical operator computes the logical or between two images $I_1$ and $I_2$.

On a binary image, it is equivalent to a maximum operation, or to the union of two sets, as it appears in the boolean table of the figure.

logical_or_image01.png

The logical OR operation

XOR 

The XOR logical operator is the exclusive or between two images $I_1$ and $I_2$ as described on the figure below.

logical_xor_image01.png

The logical XOR operation

NOR 

The NOR logical operator is the not or of two images $I_1$ and $I_2$.

NAND 

The NAND logical operator is the not and of two images $I_1$ and $I_2$.

NXOR 

The NXOR logical operator is the logical equivalence, i.e.

: Not of the exclusive or of two images $I_1$ and $I_2$.\ The logical equivalence of two binary sets A and B is described in the boolean table of the figure below.

logical_nxor_image01.png

The logical NXOR operation

SUB 

The SUB logical operator is the logical difference between images $I_1$ and $I_2$ as described on the figure below.

Note that logical difference is the only non commutative logical operation, i.e. $A-B\neq B-A$.
