What is Image Arithmetic?

Image Arithmetic is performing arithmetic operations on two or more images. Here the operation is done in a pixel-by-pixel fashion which means that the value of the pixels of the output image depends only on the values of the corresponding pixels in the input images. Here the arithmetic operation is denoted as,

I(x,y) = A(x,y) o B(x,y)

where ‘o’ is an arithmetic operation, ‘I’ is the resultant image, ‘A’ and ‘B’ are input images of identical size. Thus Image Arithmetic plays an important role in the context of ‘Image processing’. And this also has wide range of applications including computer vision, medical imaging, satellite imaging, and digital photography.

In this article we will perform arithmetic operations on two sample images using R programming.

Image arithmetic in R Programming Language involves manipulating images by performing mathematical operations on their pixel values. This can be useful for tasks like blending images, adjusting contrast, and creating special effects. In this article, we will see how image arithmetic is implemented in R.
