Tile-Compile

Tile-Compile is a toolkit for tile-based quality reconstruction of astronomical image stacks (methodology v3.3).

What is TBQR?

Tile-Based Quality Reconstruction (TBQR) replaces rigid frame selection with a robust spatio-temporal quality model. By decomposing frames into local tiles and modeling quality along two orthogonal axes—global atmospheric transparency/noise and local structural sharpness—we reconstruct a signal that is physically and statistically optimal at every pixel.

Features

  • Advanced Registration – Global + sequential alignment with astrometric fallback
  • Tile-based Reconstruction – Local quality-weighted stacking
  • Background Gradient Extraction (BGE) – Remove light pollution gradients
  • Photometric Color Calibration (PCC) – Accurate color using reference stars
  • Quality-driven Clustering – Separate frames by seeing conditions
  • Smart Telescope Optimized – For Seestar, Dwarf II, etc.
  • Resume Capability – Continue from any pipeline phase
  • Docker Support – Containerized execution
  • GUI2 Web Interface – Browser-based parameter studio
