Logic Operators X-OR,X-NOR & Bitshift Operators Prepared by Emad A.Elmotaleb Eqady.

Logical XOR/XNOR

INPUT vs OUTPUT INPUT  Binary or Grey Level Image. OUTPUT  Binary or Grey Level Image.

X-OR vs X-NOR The XOR function is only true if just one (and only one) of the input values is true, and false otherwise. the output values of XNOR are simply the inverse of the corresponding output values of XOR.

image2 New image Image 1 X-OR Or X-NOR X-OR Or X-NOR

colered Image2 colered Image colered Image X-OR Or X-NOR X-OR Or X-NOR

New Image ?????????????

The XOR (and similarly the XNOR) operator typically takes two binary or graylevel image as input, and outputs a third image whose pixel value are just those of the first image, XORed with the corresponding pixels from the second.
