AddImg

DESCRIPTION

This module computes the pointwise addition of two images. It corresponds to the ilAddImg operator in the ImageVision Library.

INPUTS

Port: First Img In
Type: Lattice
Constraints: 1..3-D
This is one image added.

Port: Second Img In
Type: Lattice
Constraints: 1..3-D
This is the other image added.

WIDGETS

OUTPUTS

Port: Img Out
Type: Lattice
Constraints: 1..3-D
This is the image sum output as a lattice. Its size is equal to the larger of the two inputs.

KNOWN PROBLEMS

If the two source images differ in the number of components then the image with the lesser number of components is promoted (by replication) to the larger prior to performing the module's operation.
