From 7c702b1bcf8c55e07e8f90271ded5f9db8206096 Mon Sep 17 00:00:00 2001 From: LLLin000 <809867916@qq.com> Date: Sun, 5 Jul 2026 22:36:17 +0800 Subject: [PATCH] fix: exclude table-owned media and inline figure body refs from figure matching MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PR-1 of the architecture review fixes. Two entry-level filters before figure matching: 1. _is_table_owned_media(): excludes media_asset blocks with table roles/raw_labels/hints from the figure asset pool. Previously these entered as figure candidates and ended up as unmatched legends/orphans. 2. _looks_like_inline_figure_body_reference(): detects body text like 'Figure 11-10 shows...' (hyphenated ranges, list ranges) and flags it as an inline reference, not a figure legend. Applied in both ocr_figures.py and ocr_roles.py for consistent early rejection.

SKXTCE6M — Table→Figure Routing ⚠️ +- **figure_001:** ✅ Clean process diagram, caption matches +- **figure_004:** ✅ Clean 8-panel stacked figure, "Fig. 4" visible +- **orphan_002:** ❌ Is actually a **table** (column headers: Material, Hydrogel type, Outcome) +- **orphan_003:** ❌ Also a **table** (biochemical stimuli summary) +- **Verdict:** 6 table titles misrouted as figure candidates. Orphans are tables cut as images. + +### 2. SRNJDAA2 — Body Text False Positives ⚠️ +- **orphan_001:** Mechanical stress diagram sub-panel (legitimate figure, should match) +- **Unmatched legends:** All `body_paragraph` with "Figure N-M shows..." text — genuine inline references +- **Verdict:** 9 FPs in legend detection. 1 orphan missed a legitimate match. 23/23 matched figures are correct. + +### 3. 3FDT9652 — Minor Gap +- **orphan_001:** ❌ Registered symbol "®" — noise, ignorable +- **orphan_002:** Unverified but likely similar noise +- **Unmatched legend:** "A, Full-thickness tear of supraspinatus..." — partial caption +- **Verdict:** 1 partial caption missed (sub-panel label "A," confuses matching). Orphans are noise. + +### 4. 6QNRHRKX — Complete Figure Detection Failure 🔴 +- **orphan_001:** ✅ Figure sub-panel (schematic lines + arrow) +- **orphan_002:** ✅ **Complete bar chart** — radiological case distribution +- **orphan_003:** Likely another figure sub-panel +- **All 7 captions unmatched.** Orphan_002 is a complete figure that should have been matched. +- **Verdict:** Short captions ("Fig. 2") provide too little text signal for matching algorithm. Figures likely in two-column layout, detection fails to find candidate regions. + +### 5. SWDN9RHF — Red ≠ Bad Figure Quality ✅ +- **figure_001:** ✅ Clean medical image (MRI bone marrow lesion) +- **Red status:** `abstract_found: False` — paper starts with author info, no abstract section +- **Verdict:** Figure matching works. Red is structural false alarm. + +### 6. SAN9AYVR — Green Confirmed ✅ +- **figure_001:** ✅ Multi-panel workflow, clean crop +- **orphans (34):** Tiny (2-7KB) — "check for updates" icon, plot markers, UI elements +- **Verdict:** True green.

"Figure N-M shows..." should be distinguished from "Figure N-M. (caption)". + +**Fix:** Filter `body_paragraph` blocks from legend candidates.

Captions are very short ("Fig. 2" through "Fig. 7") — just labels, no descriptive text. Figures appear to be embedded in two-column text layout. Orphans are sub-panels (~12KB each) that couldn't be matched. + +**Output impact:** SEVERE. Figures appear in markdown as bare `> Fig. 2` blockquotes with no image. One descriptive caption text lost entirely. + +**Root cause:** Short label-only captions lack the text overlap that the matching algorithm uses to pair captions with figure regions. Possibly combined with figures not detected as image regions by page layout analysis. + +**Fix:** Needs investigation of the actual PDF layout — short captions in radiology papers may need a different matching heuristic. + +--- + +## 4. 3FDT9652 — Single Caption Gap ⚠️ + +**Paper:** (Rotator cuff / shoulder tendon paper) + +**Finding:** 6/8 figures matched. One unmatched legend: "A, Full-thickness tear of supraspinatus tendon..." — this is a partial caption starting with a sub-panel label. 2 orphans exist. + +**Output impact:** 1 figure caption lost from rendered output. + +--- + +## 5. SWDN9RHF — Structural Red, Figure Quality Good ✅ + +**Paper:** Roemer et al. — *MRI-based semiquantitative assessment of subchondral bone marrow lesions* + +**Finding:** RED status is structural (`abstract_found: False`, `structural_blockers: 2`), not OCR quality. The single figure (Fig. 1) is correctly matched and cropped. The paper has no abstract section in the traditional sense. + +**Output impact:** None for figure matching.

SAN9AYVR — Green but High Orphan Count ✅ + +**Paper:** (Large review, 81 pages, 31 matched figures) + +**Finding:** All 31 figures correctly matched. 34 orphans exist but are tiny (2-7KB) — likely small icons, section dividers, plot markers.
