findFP: Find and remove firing pin region

In xhtai/cartridges: Algorithm to Compare Cartridge Case Images

Description

After finding the primer region using findPrimer(), we now remove the firing pin impression, returning a 1919 x 1919 matrix, where areas that are not part of the breechface impression are set to 0. Pixel values range from 0 to 255. For more information on the steps involved in finding the firing pin region, refer to the GitHub page.

Usage

findFP(fileName, primer)

Arguments

fileName	location of image file. This function has been tested on png files.
primer	binary image in EBImage format, as returned by findPrimer

A 1919 x 1919 matrix, in the original orientation, i.e. a cropped version of the original 1944 x 2592 image.
