IPerode performs erosion or "region shrinking" morphological operations on ip_Images based on one of four arbitrary structuring elements.

&in_image: The input is a reference to an ip_Image. The ip_Image can be considered to be of two types:
logical: This is an ip_Image whose bands are bytes, each of which contains one of two values: 0 or 255. Such logical or "binary" ip_Image are produced by IPthreshold and IPmorph.

In the case of a logical ip_Image, the output of IPerode is the logical "and" of all of the neighborhood pixels selected by the structuring element.

Any other input ip_Image is said to be a "grayscale," meaning only that each band contains data of any type that can be interpreted as a set of grayscale values. For a grayscale ip_Image, the output is the minimum of all the neighborhood pixels selected by the structuring element.

&in_roi: ip_Roi. An optional region of interest. The data must be of type byte.

FilesRB: UIradioBox. Selects which of four arbitrary structuring element files to use for the erosion. The choices are:

Cross 3x3 (default)
Cross 5x5
Rectangle 3x3
Rectangle 5x5

dst: The output is a new ip_Image of the same dimensions, type, and number of bands as the input ip_Image. Edge pixels are set to 0.
TmpField: This output is the ip_Image converted back into an AVS/Express field.
obj: This is a renderable version of the output.
