Unique: Uses spatial analysis and cross-page content matching to identify artifacts rather than simple regex patterns. Configurable heuristics allow tuning sensitivity per document type, balancing artifact removal against false positives.

vs others: More sophisticated than regex-based header/footer removal; configurable unlike fixed-rule systems; preserves legitimate repeated content better than aggressive filtering.

Unique: Combines spatial heuristics (position-based detection) with VLM-based content analysis to classify headers/footers, avoiding false positives from pure position-based approaches. The system learns header/footer patterns across pages rather than applying fixed rules.

vs others: More accurate than fixed-region removal because it adapts to document-specific header/footer placement; more robust than content-based filtering alone because it uses spatial consistency as a signal.
