Enhancement Recommendations
To improve detection rate from 21% to >90%, focus on:
- Color Analysis - Add RGB comparison for all color properties
- CSS State Detection - Extract hover, focus, active states
- Form Field Analysis - Detect input, select, checkbox styling
- Border & Shadow Details - Parse CSS for exact measurements
- Responsive Behavior - Test at multiple breakpoints
- Animation Detection - Analyze CSS animations and transitions
- Accessibility - Check ARIA attributes and contrast ratios
- DOM Structure - Compare element hierarchy and nesting
Detection Methods
- Screenshot Analysis: Pixel-level comparison using OpenCV
- CSS Extraction: Parse computed styles from website
- HF Vision Model: Semantic understanding of visual differences
- DOM Analysis: Compare HTML structure and attributes
- Color Analysis: RGB/HSL comparison and contrast checking
- Pixel Comparison: Direct pixel-by-pixel analysis
Implementation Status
- ✅ Screenshot Analysis: Implemented
- ✅ CSS Extraction: Implemented
- ✅ HF Vision Model: Integrated
- ⚠️ DOM Analysis: Partial
- ❌ Color Analysis: Needs enhancement
- ❌ Advanced State Detection: Not implemented
