- New module: modules/ai_upscaler.py
- Real-ESRGAN integration for AI-powered upscaling
- Designed specifically for low-res game textures/icons
- 4x upscale factor with neural network enhancement
- Falls back gracefully if model not available
- Updated TGA Converter UI:
- New "AI Enhanced (Real-ESRGAN)" option in upscale dropdown
- Only shown if Real-ESRGAN is installed
- AI upscaling happens before canvas placement
- Shows progress during AI model loading
Real-ESRGAN is much better than basic methods for rendered (non-pixel) icons!
To use AI upscaling:
1. pip install torch torchvision --index-url https://download.pytorch.org/whl/cpu
2. pip install realesrgan
3. Download RealESRGAN_x4plus.pth model
4. Select "AI Enhanced" in the UI
