# LiveFace

**Real-Time Photorealistic Facial Animation on Low-End Mobile Devices**

*Patent Pending (USPTO) | [Paper (Zenodo)](https://doi.org/10.5281/zenodo.19477081) | [Website](https://creatora.app)*

## What is LiveFace?

LiveFace is a patent-pending neural rendering system that turns **a single photo into a photorealistic talking avatar** running at 30 fps on budget mobile devices — fully offline, no cloud required.

## Architecture

Four compact per-avatar neural decoders + one shared compositor-upscaler:

| Module | Parameters | Output | Function |
|--------|-----------|--------|----------|
| MouthDecoder | 5-12M | 128x96 RGBA | Lip sync, jaw, emotions |
| EyeDecoder | 1.3-2M | 192x80 RGBA | Blink, gaze, wink |
| HairDecoder | 3-5M | 192x192 RGBA | Hair physics, inertia |
| BodyDecoder | 3-12M | 256x64 RGBA | Breathing, shoulders |
| Compositor-Upscaler | ~7M (shared) | 360x640 (9:16) | Seam blending, upscale, lighting |

**Total: ~20M INT8 parameters | ~19ms per frame on Snapdragon 439**

## Key Features

- **Photorealistic** — neural rendering, not cartoon or stylized
- **Real-time** — 30+ fps on budget phones ($100+)
- **Offline** — fully on-device, no cloud, no internet
- **One photo** — create avatar from a single selfie
- **Identity embedding** — 128-dim learnable per-avatar parameter
- **Dual input** — viseme-based (audio) or landmark-based (MediaPipe)
- **Portrait 9:16** — optimized for mobile displays

## Training

Per-avatar decoders are trained via **knowledge distillation**:
1. Server-side teacher model generates diverse training data from RAVDESS emotional speech videos
2. Per-frame quality filter (Haar + blur + SSIM) ensures data integrity (~0.6% rejection)
3. Student decoders learn from teacher-generated pairs with L1 + perceptual loss
4. Each avatar trains in ~40 minutes on a single GPU

## Performance

| Device | Compute | Latency | FPS |
|--------|---------|---------|-----|
| Snapdragon 439 | ~10 GFLOPS | ~19ms | 30+ |
| Snapdragon 665 | ~22 GFLOPS | ~12ms | 30+ |
| Snapdragon 778G | ~65 GFLOPS | ~4ms | 60+ |
