# Technical Document Extraction: Image Analysis
## Section 1: Data Curation & Pre-filtering
### Components:
1. **Data Sources**:
- Chameleon Fake2M GenImage
- Autoregressive GAN Diffusion
2. **Pre-filtering Categories** (Color-Coded):
- **Local artifacts** (Red)
- **Geometry flaws** (Orange)
- **Spectral clues** (Yellow)
- **Pixel noise** (Green)
- **Spatial consistency** (Blue)
- **Shadow logic** (Purple)
- **Texture fusion** (Pink)
- **High-pass fusion** (Cyan)
### Legend:
- **Circular Chart** with 8 color segments (Red-Orange-Yellow-Green-Blue-Purple-Pink-Cyan)
- Labels correspond to pre-filtering categories
- Positioned at bottom-left of diagram
## Section 2: Expert-grounded Evidence Collection
### Flowchart Components:
1. **Input Path**:
- Local artifacts → Spectral clues → Spatial consistency → Geometry flaws → Shadow logic → Texture fusion → High-pass fusion
2. **Expert Analysis Nodes**:
- **Local artifacts**: "Bird's eyes reflection missing"
- **Spectral clues**: "Periodic artifacts revealed along spectral axis"
- **Geometry flaws**: "Spatial consistency test detects irregularities"
- **Shadow logic**: "Shadow consistency test detects over-lighting patterns"
- **Texture fusion**: "Fine-grain texture irregularities"
- **High-pass fusion**: "Smooth area contains no forgery signs"
3. **Output**:
- Chain-of-Evidence Synthesis (visual evidence examples)
## Section 3: Chain-of-Evidence Synthesis
### Visual Evidence Examples:
1. **Bird Images** (4 examples):
- Annotated with green bounding boxes
- Highlighted regions: Eyes, feathers, background
### Think/Answer Process:
1. **Initial Observation** (Step 1):
- Checks texture and lighting anomalies
2. **Detailed Inspection** (Step 2):
- Identifies uniform surfaces and missing imperfections
3. **Spatial Analysis** (Step 3):
- Compares object-background alignment and projection logic
4. **Shadow Consistency** (Step 4):
- Detects over-lighting patterns
5. **High-frequency Analysis** (Step 5):
- Examines fine-grain texture irregularities
6. **Frequency Spectrum Evaluation** (Step 6):
- Reveals abnormal energy distributions
### Final Determination:
- **Synthetic Image** (Green checkmark)
- **Real Image** (Red cross)
## Legend Spatial Grounding:
- Position: Bottom-left quadrant
- Color Mapping:
