Compares images with a given metric. If the number of images in the two inputs match. a 1-to-1 comparison will be performed. If the numbers dont match every images in input 1 will be compared to every image in input 2. Thereby the number of images in input 1 needs to be bigger number of images in input 2. | Compares images with a given metric.
