Detailed Description

Multiply images with different dimensions.

Multiplication of 2 images with different dimensions (volume with plan, volume color with volume...). The image with the highest dimensions is always have to be the first one.

The output image values are given by:

See Addition between images with different dimensions for an illustrated example.
