Use this operator when you want to correct the background of an image prior to counting or measuring objects.
When used as the Image.Background operator, this operator uses its parent Image as both source and destination, unless a different source image is provided in the optional parameter. If another image is passed as a parameter to one of its methods, it is used as the source of the operation, and the result is written back to its parent image.
It can also be created independently using CreateOperator. In this case the operator does not have a parent and the parent image to be used as source and destination must be supplied in the parameter.
