In CSAFE-ISU/cmcR: An Implementation of the 'Congruent Matching Cells' Method

Remove observations from the exterior of interior of a breech face scan

Description

Remove observations from the exterior of interior of a breech face scan

Usage

preProcess_crop(x3p, region = "exterior", offset = 0, ...)

Arguments

x3p	an x3p object containing the surface matrix of a cartridge case scan
region	dictates whether the observations on the "exterior" or "interior" of the scan are removed
offset	an integer (positive or negative) value to add to the estimated radius of the associated region
...	internal usage

Value

An x3p object containing the surface matrix of a breech face impression scan where the observations on the exterior/interior of the breech face scan surface.
