Image Arithmetic

Add, subtract, multiply, and divide images

Image arithmetic is the implementation of standard arithmetic operations, such as addition, subtraction, multiplication, and division, on images. Image arithmetic has many uses in image processing both as a preliminary step in more complex operations and by itself. For example, image subtraction can be used to detect differences between two or more images of the same scene or object.

Functions

`imabsdiff`	Absolute difference of two images
`imadd`	Add two images or add constant to image
`imapplymatrix`	Linear combination of color channels
`imcomplement`	Complement image
`imdivide`	Divide one image into another or divide image by constant
`imlincomb`	Linear combination of images
`immultiply`	Multiply two images or multiply image by constant
`imsubtract`	Subtract one image from another or subtract constant from image
