Claim 11:
12. A non-transitory computer-readable storage medium storing a computer program comprising instructions which, when executed by a computer, cause the computer to perform operations including:
generating a histogram of oriented gradients feature map of the digital image, wherein the sidewall has one or more embossed and/or engraved markings;
inputting the histogram of oriented gradients feature map into a trained neural network, wherein the trained neural network is configured to output a first probability based on the input histogram of oriented gradients feature map that a region of pixels of the digital image contains the embossed and/or engraved markings; and
if the first probability is at or above a first predetermined threshold, accepting the region of pixels as the region of interest.
