process-faces.py Changes:

• Complete rewrite with different face extraction method that processes images individually instead of batch pickle storage
• Argparse implemented (--limit, --input, --model)
• Added 20% padding around the detected faces
• Consistent naming format for the output files using the NamUS ID
  • This is done because in our pipeline, we use this ID to match the faces to the correct person
• Implemented automatic NamUs ID extraction from filepath / filename
• Implemented skipping for duplicates

scrape-data.py Changes:

• Argparse implemented (--limit)

scrape-files.py Changes:

• Argparse implemented (--limit)
