Upsampling
8192×4096 native, up to 16384×8192+ with Real-ESRGAN upscaling
Upsampling uses Real-ESRGAN, an AI upscaling model, to enhance your panoramas while addressing boundaries through tile-aware geometry. Transform 4K images into rich 8K or 16K+ outputs with enhanced texture and visual depth.

Key Features
Neural Upscaling
Real-ESRGAN uses deep learning to intelligently upscale images, adding convincing detail and texture rather than simple interpolation blur.
Detail Enhancement
Enhance textures, sharpen edges, and recover fine details lost during compression or lower-resolution rendering.
How It Works with Hexagonal Tiling
Wrap-Aware Upscaling
Unlike standard upscalers that process the entire image at once, our system intelligently handles the equirectangular projection, processing tile boundaries across the 360-degree wrap.
-
1
Tile-Aware Processing
Each hexagonal tile is upscaled with overlap awareness
-
2
Edge Blending
Blended across tile boundaries
-
3
Pole Handling
Special care for zenith and nadir regions
-
4
Wrapped Output
Wrap-aware tile processing
Use cases
