  1. Ndeipi basa rekutanga reOCR?
    • Kushandura mifananidzo yemavara kuita macode anoverengwa nemuchina
    • Kumanikidza mifananidzo kuti vatore nzvimbo shoma yekuchengetera
    • Kudzima mavara anonzwisisika mumagwaro otomatiki
    • Kuturikira mazwi anotaurwa kuita zvinyorwa zvidiki
  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. Sei 'de-skewing' iri yakajairika nhanho yekufambisa muOCR mapaipi?
    • Inowedzera ruvara kune-black-and-white scans
    • Inovharidzira gwaro kuitira kuvanzika
    • Inotwasanudza mavara akarereka kana kutenderedzwa kuti zvive nyore kuverenga
    • Inowedzera kugadzirisa kwefaira kupfuura kwepakutanga
  4. Ndeipi yeiyi inonyanya kushandiswa yakavhurika-sosi OCR injini?
    • TensorBoard
    • Photoshop
    • FFmpeg
    • Tesseract
  5. Nei mavara akanyorwa nemaoko achiwanzoomera OCR pane akadhindwa?
    • Maumbirwo emavara anosiyana zvakanyanya pakati pevanyori uye kazhinji anobatana kana kupindirana
    • Kunyora nemaoko nguva dzose kunoshandisa mavara einki asina kujairika
    • Runyoro runogara rwakakura pane zvakadhindwa
    • Makamera haakwanise kutarisa pamapeji akanyorwa nemaoko
  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
