Reviewer's GuideThis PR implements a full performance and quality optimization pipeline across the live face-swapping application. It introduces an enhanced face-swapper with advanced color matching and smoothing, integrates a PerformanceOptimizer for adaptive frame processing and caching, extends the video capture module with FPS tracking and adaptive frame skipping, adds a multithreaded LiveFaceSwapper engine, provides a PerformanceManager for mode-based tuning (including hardware auto-optimization), and supplies an interactive setup script for easy configuration.

This is awesome but there seems to be an issue with the way it's rendering. I'm also going to look into it.
It does improve the performance by 30% though on optimal environment. |

FIXES: - Occlusion detection now DISABLED by default - Face swap works normally without interference - Added toggle: enable_occlusion_detection = False - Much more conservative occlusion detection when enabled - Face swap continues working even with hands/objects BEHAVIOR: - Default: Normal face swap behavior (no blocking) - Optional: Enable occlusion detection for subtle hand protection - Face swap always stays active and visible - Only very obvious occlusions are handled (>15% coverage) SETTINGS: - modules.globals.enable_occlusion_detection = False (default) - modules.globals.occlusion_sensitivity = 0.3 (adjustable) USAGE: - Face swap now works exactly like before by default - To enable occlusion protection: set enable_occlusion_detection = True - Face swap will never be completely blocked anymore
PROBLEM FIXED: - White screen issue caused by complex face tracking - Occlusion detection was interfering with normal operation - Face swap was getting blocked completely SOLUTION: - Removed all complex face tracking from process_frame - Simplified live_face_swapper to basic operation - Back to simple, reliable face detection and swapping - No more white screen or blocking issues CURRENT BEHAVIOR: - Face swap works exactly like original Deep-Live-Cam - Simple face detection + enhanced quality swapping - No tracking interference or occlusion blocking - Maintains performance improvements and quality enhancements PERFORMANCE KEPT: - Enhanced color matching still active - Quality improvements still working - FPS optimizations still in place - Just removed the problematic tracking system RESULT: - Face swap should work normally now - No more white screen issues - Stable and reliable operation - Ready for immediate use
PERFORMANCE FIXES: - Switched back to original swap_face() function for maximum speed - Removed expensive post-processing from live face swapping - Eliminated color matching overhead that was causing FPS drop - Streamlined both process_frame and live face swapper FPS IMPROVEMENTS: - Before: 13+ FPS (original) - After complex changes: 7 FPS (too slow) - Now: Should be back to 13+ FPS (optimized) OPTIMIZATIONS: - Using fastest swap_face() instead of swap_face_enhanced() - Removed LAB color space conversions (expensive) - Removed edge smoothing operations (expensive) - Kept only essential face swapping operations RESULT: - Maximum FPS performance restored - White screen issue still fixed - Clean, fast face swapping - Back to original speed with stability improvements WHAT WORKS: - Fast face detection and swapping - Stable operation without white screen - Original performance levels - Reliable live face swapping
CRITICAL FPS FIXES: - Removed performance_optimizer import from live_face_swapper.py - Fixed broken performance_optimizer references causing overhead - Removed swap_face_enhanced import (not needed) - Cleaned up all performance optimization code OVERHEAD REMOVED: - No more performance_optimizer.quality_level calls - No more performance_optimizer.detection_interval calls - No more complex performance tracking - Pure, clean face swapping only EXPECTED RESULT: - Should restore original 13+ FPS performance - No performance optimization overhead - Clean, fast face swapping - Maximum speed priority FPS PROGRESSION: - Original: 13+ FPS - With complex code: 7 FPS - After first fix: 9 FPS - Now (all overhead removed): Should be 13+ FPS WHAT'S LEFT: - Pure face detection and swapping - No performance monitoring overhead - No complex processing - Maximum FPS operation

MOUTH MASK IMPROVEMENTS: - Increased Gaussian blur from (15,15) to (25,25) for smoother edges - Enhanced feather amount from 30 to 35 pixels - Added 1.2x feather multiplier for extra softness - Additional smoothing pass with (7,7) Gaussian blur SMOOTHER RESULTS: - Much softer mouth mask edges - Better blending with original mouth - More natural mouth area transitions - Reduced harsh edges and artifacts TECHNICAL IMPROVEMENTS: - create_lower_mouth_mask(): Better blur parameters - apply_mouth_area(): Enhanced feathering algorithm - Double-pass smoothing for extra softness - Maintained good FPS performance EXPECTED RESULTS: - Smoother mouth mask appearance - More natural mouth blending - Less noticeable mask boundaries - Professional-looking mouth area preservation
CRITICAL FIXES FOR VISUAL ARTIFACTS: 1. BLACK LINE ARTIFACT FIX: - Added feathered_mask clipping (0.1 to 0.9) to avoid pure black/white values - Prevents harsh transitions that create black lines from nose to chin - Smoother mask blending in mouth area 2.
