Unused at the moment.
A single-channel (GRAY) 8-bit (8U) Image object
with the same dimensions as x. This can be used to mask out pixels
that should not be considered when calculating the mean (pixels set to 0 in
the mask will be ignored during the mean calculation).
A numeric value (for single-channel images) or a vector of numeric values (for multi-channel images).
