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.
|Absolute difference of two images
|Add two images or add constant to image
|Linear combination of color channels
|Divide one image into another or divide image by constant
|Linear combination of images
|Multiply two images or multiply image by constant
|Subtract one image from another or subtract constant from image
