WebThe addWeighted function is a function that helps in adding two images and also blending those by passing the alpha, beta and gamma values. In order to analyse images, this helps in adjusting the gradients and in the processing of the image. The blending of the images depends on alpha and beta values which are passed as arguments to this function.
