Two images or volumes of the same size and number of channels. The first input image is the reference.

Output

Modified window/level values for second image

The input sets will not be modified by this algorithm.

Description

Changes the window and level setting of the second data set to match the intensities of the first data set (reference) as closely as possible in a squared intensity difference sense. 

Works best when the images show the same or similar content but the overall brightness and contrast differ.
