Preprocessing now tries progressively heavier variants per receipt (plain -> high-pass -> edge-enhance -> both), stopping as soon as a cheap LLM-free arithmetic check on the OCR text looks plausible, so the extra processing only applies to receipts that need it. A flat version of the same heavier processing regressed the full batch by helping hard receipts but hurting easy ones; the adaptive version improves date-matching 37/52 -> 40/52 with no regression (see testing/2026_10_04_gimp_highpass_nlfilter_experiment.md). Also adds test_ocr.sh and test_single.sh for checking a single receipt's OCR text or full pipeline result without a batch run.

# Test-only tool: runs preprocessing + OCR (1_preprocess_image.sh,
|
|
# 2_ocr_image.sh - variant 0/baseline only, deliberately not
|
|
# 12_adaptive_preprocess_ocr.sh) on a single receipt photo and prints the
|
|
# raw OCR text to stdout - no LLM extraction step, no ground-truth
|
|
# comparison, and no files left behind (unlike test_single.sh/
|
|
# test_batch.sh, which persist scratch/result directories and go through
|
|
# the real adaptive pipeline). Useful for quickly checking what Tesseract
|
|
# actually reads off one specific preprocessing variant in isolation -
|
|
# e.g. while iterating on tooling-container/src/preprocess.py - without
|
|
# the adaptive step's variant selection in the way, waiting on the LLM
|
|
# call, or needing ground truth.

# Usage: ./test_ocr.sh -in <photo.jpg>
