ImageDifference
ImageDifference
gives an image in which each pixel is the absolute difference of the corresponding pixels in
and
.
MORE INFORMATION
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
.
If
and
are both multichannel images, the values in each channel are compared separately.
ImageDifference
gives an image with the largest type of either
or
.
For binary images,
ImageDifference
effectively finds the logical XOR of pixel values.
