- Enhanced geometric feature extraction for comprehensive mouth shape analysis
- Implemented vowel classification (A, E, I, O, U) based on lip geometry
- Added new SRT format option to display detected viseme sequences
- New toggle for enabling/disabling viseme detection
- Caching system supports viseme detection state
- Viseme sequences grouped for readability (A3-E2-I-O4)
Technical implementation:
- Extract 8 geometric features: lip width/height, mouth area, roundedness, curvature
- Rule-based vowel classification with confidence scoring
- Frame-by-frame viseme detection integrated with existing movement analysis
- ~20% performance impact when enabled, fully cached for repeated analysis
