Image Processing Toolbox Release Notes    

Integer Image Arithmetic

The Image Processing Toolbox 3.1 includes new functions for performing arithmetic on image arrays without converting them to double-precision. In addition to the basic operations (add, subtract, multiply, and divide), there are several key functions (absolute difference, linear combination, and complementation) that cannot readily be implemented in terms of the basic operations.

Function
Description
imabsdiff
Absolute difference of two images
imadd
Add two images, or add constant to image
imcomplement
Complement image
imdivide
Divide two images, or divide image by constant
imlincomb
Linear combination of images
immultiply
Multiply two images, or multiply image by constant
imsubtract
Subtract two images, or subtract constant from image
