This function computes the weighted sum of two
 Image objects.
addWeighted(image1, image2, weight = c(0.5, 0.5))| image1 | An  | 
|---|---|
| image2 | An  | 
| weight | A 2-element vector of the respective weight of each image (default: c(0.5, 0.5)). If the two weights do not add up to 1, they will be rescaled accordingly. | 
An Image object.
