This Unit is a Gradient Edge Detector. It looks for the 'rates of change' in the intensities of the image. These will be high where there are 'edges' in the image. An alternative method of edge detection is the Binary Edge Detector, a network for which can be seen on the ShrinkWhite help page.

Example

In this example some post processing has taken place as GradientEdge quite often generates a very dark image.
