Fix low-quality OCR before approval

Some pages are not worth auto-processing twice—know when a new photo beats another automated pass.

Low-quality OCR is fixed or rejected before approval. You stop patching hopeless captures and know when a new photo beats another automated pass.

How to do it

Work through one batch at a time. Finish review before you upload the next set of pages.

  1. Flag captures with blur, shadow, or cut-off characters for re-shooting first.

  2. Re-run extraction only after improving capture quality—not repeatedly on the same bad photo.

  3. Compare each draft field to the source; edit only when the underlying text is unambiguous.

  4. Reject cards where OCR invented characters you cannot verify on the image.

  5. For mixed layouts, split Thai and English into predictable front/back roles.

  6. Approve the reduced, trustworthy set; export or study without carrying OCR debt forward.

Quick check before you approve

  • No approved card relies on guessed tone marks or unreadable source regions.
  • Re-captured pages show visible quality improvement over rejected originals.
  • Rejected cards outnumber sloppy approvals in problematic batches.

When something goes wrong

Same error after re-run

the photo is still bad—lighting or crop must change.

Partial line readable

crop tighter to the readable region instead of approving the whole block.

Too many rejects

slow down capture habits before scaling uploads again.
