    • Lati blur ọrọ ifura ni awọn iwe aṣẹ laifọwọyi
    • Lati tumọ ohun ti a sọ sinu awọn atunkọ kikọ
  2. Which architecture lets OCR recognize a sequence without explicit character segmentation?
    • A fixed one-template-per-character lookup
    • A sequence recognizer trained with CTC or an attention decoder
    • A region-proposal network only
    • A color threshold rule
  3. Kini idi ti 'de-skewing' jẹ igbesẹ iṣaaju ti o wọpọ ni awọn opo gigun ti OCR?

  6. What does the OCR-free Donut model do in document understanding?
    • It only de-skews images and never reads text
    • It processes a document image directly to produce task-specific text outputs without a separate OCR stage
    • It requires Tesseract output as its input for every task
    • It detects motion vectors between consecutive document frames
  7. What is CTC useful for in OCR?
    • Encrypting scanned pages
    • Correcting every spelling error
    • Training sequence predictions when input-frame and output-character alignment is not given
    • Finding legal signatures
  8. Why should OCR output be checked against the source image?
    • OCR always omits spaces
    • The source image is never available
    • Text recognition is legally inadmissible
    • Recognition can still err on degraded, unusual, or handwritten text
