Ua raws li qhov xav tau, qhov kev lees paub kho qhov muag yog dab tsi sau lub npe ntawm peb cov khoom siv kho qhov muag pom?

Hom ntawm cov khoom siv kho qhov muag pom:

  • MICR (Magnetic Ink Character Recognition): Siv los ntawm cov tsev txhab nyiaj los nyeem cov lej sau rau ntawm daim tshev.
  • OCR (Optical Character Recognition):
  • OMR (Optical Mark Recognition):
  • Intelligent character recognition (ICR):
  • Intelligent word recognition (IWR):
