date/time, price per litre, litres, discount, total) from German fuel receipt photos: grayscale + mild bilateral filter + contrast stretch, Tesseract OCR, then LLM structuring via a small local model (Qwen 2.5, served by Ollama). Each step is independently runnable and inspectable through numbered scripts against a shared tooling container.

# Test-only tool: runs the full container pipeline (1_preprocess_image.sh,
|
|
# 2_ocr_image.sh, 3_extract_data.sh) over every *.jpg in a test-data
|
|
# directory, then compares the results against that directory's
|
|
# ground-truth spreadsheet (benzin_kosten.ods). Everything -
|
|
# preprocessing, OCR, structuring, and the comparison itself - runs
|
|
# inside the tooling container; nothing here depends on a host Python

# (01_gray.png, 02_bilateral.png,

# 03_final.png, ocr.txt) for
|
|
# inspecting each step on its own
