Why is barcode scanning so quick and accurare, but OCR even for digital text is kinda bad?
In: Technology
There is a massive difference in complexity between the two. Bar codes are 1 dimensional variations (thickness of a given line) while OCR must establish the edges of each purported character, it’s relationship to other characters, font variations, bad handwriting, etc. In the true ELI5 spirit, I’d say that bar codes are checkers while OCR is chess.
