Bitwise exlusive orSee full documentation

image =

bitwiseXOrImgImg (inIntImg1,inIntImg2)

Detailed Description

Bitwise exclusive or operation on 2 input images

On output image values are given by:

(with corresponding to the Bitwise xor operator)

Input and output images must have same size and buffer type. Buffers must be of type integer

A Bitwise xor operator applied to 2 integers performs the logical exclusive or operation on each pair of corresponding bits of the binary representation of these 2 integers. As shown in the truth table below, the result in each position is 1 if one and ONLY one bit among the 2 bits is 1; otherwise, the result is 0.

Input bit #1	Input bit #2	Output bit :
0	0	0
0	1	1
1	0	1
1	1	0

For instance, if we compute the result of a Bitwise xor on the two integers 5 and 3, we obtain;

  0101 (decimal 5)
^ 0011 (decimal 3)
= 0110 (decimal 6)

Here is an example of a Bitwise exlusive or operation applied to two 2D binary images (black pixels have value 0, white pixels have value 1):

Example of Python code :

Example imports

import PyIPSDK
import PyIPSDK.IPSDKIPLLogical as logic

Code Example

    # opening of input images
    inImg1 = PyIPSDK.loadTiffImageFile(inputImgPath1)
    inImg2 = PyIPSDK.loadTiffImageFile(inputImgPath2)
    
    # bitwize 'xor' computation
    outImg = logic.bitwiseXOrImgImg(inImg1,  inImg2)

Header file

#include <IPSDKIPL/IPSDKIPLLogical/Processor/BitwiseXOrImgImg/BitwiseXOrImgImg.h>

Code Example

        // open input images
        ImageGeometryPtr pImageGeometry = geometry2d(inType, sizeX, sizeY);
        ImagePtr pInImg1 = loadRawImageFile(in1Path, *pImageGeometry);
        ImagePtr pInImg2 = loadRawImageFile(in2Path, *pImageGeometry);

        // compute bitwise exclusive or on input images
        ImagePtr pOutImg = bitwiseXOrImgImg(pInImg1, pInImg2);
