How It Works
From Raw Video to Pixel-Level Understanding
Body Pix processes each video frame through a multi-stage pipeline that detects people, segments their body parts, estimates pose, and delivers structured output — all in under 30 milliseconds.
Person Segmentation
Instantly separate people from backgrounds with pixel-level precision. Works across diverse lighting conditions, complex backgrounds, and partial occlusions to deliver clean foreground masks for any downstream application.
- Pixel-level foreground/background masks
- Handles partial occlusions and overlaps
- Robust across lighting conditions
- Alpha matte generation for soft edges
- Single-frame and temporal consistency modes
Body Part Labeling
Classify every pixel belonging to a person into one of 24 distinct body part regions. From head and torso to individual limbs and hands, get granular anatomical understanding for precise spatial reasoning.
- 24-class body part taxonomy
- Head, torso, arms, hands, legs, feet regions
- Left/right limb differentiation
- Sub-pixel boundary refinement
- Confidence scores per region
Pose Estimation
Detect and track 17 skeletal keypoints per person with high-fidelity joint localization. Combine pose data with segmentation masks for rich spatial understanding of human posture and movement.
- 17 skeletal keypoints per person
- Joint angle and limb length estimation
- Pose confidence scoring
- Multi-person pose graphs
- Temporal pose smoothing
Background Removal
Remove, replace, or blur backgrounds in real time without green screens. Produce broadcast-quality results suitable for video conferencing, content creation, and live streaming applications.
- Real-time background replacement
- Gaussian and bokeh blur modes
- Virtual background insertion
- Hair and edge refinement
- Green-screen-free compositing
Multi-Person Tracking
Detect, segment, and independently track multiple people in the same frame. Maintain consistent identity assignment across frames even through occlusions and rapid movement.
- Per-instance segmentation masks
- Persistent identity assignment
- Occlusion-aware re-identification
- Crowd-density handling
- Entry/exit detection
Real-Time Processing
Process video streams at 30+ FPS on standard hardware with optimized inference pipelines. GPU and CPU execution paths ensure deployment flexibility from edge devices to cloud infrastructure.
- GPU and CPU inference paths
- WebGL and WebAssembly support
- Edge device optimization
- Batch processing for offline workflows
- Adaptive quality scaling

Example Scenarios
How Body Pix segmentation works in practice
Virtual Try-On for Retail
Challenge
A major fashion retailer experienced 38% return rates on online apparel orders because customers could not visualize how garments would fit their body shape. Static size guides and 2D overlays failed to capture realistic draping and proportions.
Solution
Deployed Body Pix to segment individual body parts in real time via the customer's webcam. The 24-class body part map enables precise garment overlay that respects anatomical proportions, joint positions, and natural movement for a true-to-life virtual fitting room.
Results
"Customers finally trust what they see online. Our return rate dropped by half within the first quarter of deployment." — VP of Digital Commerce, Global Fashion Retailer
Fitness & Sports Analytics
Challenge
A fitness technology company needed to provide real-time form correction during home workouts. Existing pose-only solutions missed critical body positioning details like shoulder alignment and hip rotation that cause injuries.
Solution
Combined Body Pix body part segmentation with pose estimation to deliver pixel-level anatomical tracking. The system detects muscle group engagement, joint angles, and body alignment in real time, providing instant corrective feedback during exercise.
Results
"Body Pix gave us the anatomical detail that pose estimation alone could never provide. Our injury rate dropped dramatically." — CTO, Connected Fitness Platform
Video Conferencing Backgrounds
Challenge
A unified communications provider needed to offer virtual backgrounds that worked reliably across diverse hardware, lighting conditions, and user environments—without requiring green screens or dedicated GPUs on endpoint devices.
Solution
Integrated Body Pix person segmentation to deliver real-time background removal and replacement running entirely in the browser via WebGL. The solution handles hair detail, semi-transparent edges, and rapid movement without artifacts.
Results
"We eliminated the green screen requirement entirely. Background replacement just works, on any laptop, in any room." — Director of Product, Enterprise Collaboration Suite
