BUILT-IN MATHEMATICA SYMBOL
ImageDifference
ImageDifference[image1, image2]
gives an image in which each pixel is the absolute difference of the corresponding pixels in 
and 
.
Details
- The images
and 
must have the same dimensions. - ImageDifference works with arbitrary single-channel or multi-channel images.
- If
or 
is a single-channel image, the absolute difference is computed from each channel of the other image in ImageDifference[image1, image2]. - If
and 
are both multichannel images, the values in each channel are compared separately. - ImageDifference[image1, image2] gives an image with the largest type of either
or 
. - For binary images, ImageDifference effectively finds the logical XOR of pixel values.
