GraXpert

Standalone astronomical denoising and background correction

Vendor documentationChecked Nov 2, 2026By AIPicksy Editorial

What it does

GraXpert provides AI denoising and background extraction for astronomical images in a standalone desktop application. It also includes traditional sample-based interpolation methods and command-line processing. The current repository distinguishes deterministic sample-free background extraction from trained AI models; not every automatic operation is AI.

Who it is for

Astrophotographers wanting a free focused cleanup step alongside an existing processor

What stands out

  • AI denoising with adjustable strength
  • Background extraction and sample-based interpolation
  • GUI and command-line operation
  • Windows, Linux and separate macOS builds

Limitations to consider

  • Not a complete calibration and stacking suite
  • Large denoising batches can exhaust memory
  • Automatic sample-free ONNX processing is not itself a trained AI model
