Benjamin Admin	d39d249daa	feat: add pass 3 text-line regression to deskew pipeline ... After iterative projection (pass 1) and word-alignment (pass 2), a third pass uses Tesseract word positions + linear regression per text line to measure and correct residual rotation. This catches cases where passes 1-2 leave significant slope (e.g. 1.7° residual on heavily skewed scans). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-05 17:53:11 +01:00
Benjamin Admin	538d5c732e	feat: two-pass deskew with wider angle range and residual correction ... - Increase iterative deskew coarse_range from ±2° to ±5° to handle heavily skewed scans - New deskew_two_pass(): runs iterative projection first, then word-alignment on the corrected image to detect/fix residual skew (applied when residual ≥ 0.3°) - OCR pipeline API auto_deskew now uses deskew_two_pass by default - Vocab worksheet _run_ocr_pipeline_for_page uses deskew_two_pass - Deskew result now includes angle_residual and two_pass_debug Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-05 17:34:57 +01:00
Benjamin Admin	b7ae36e92b	feat: use OCR pipeline instead of LLM vision for vocab worksheet extraction ... process-single-page now runs the full CV pipeline (deskew → dewarp → columns → rows → cell-first OCR v2 → LLM review) for much better extraction quality. Falls back to LLM vision if pipeline imports are unavailable. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-05 15:35:44 +01:00
