Standalone Windows builds of the GALOSH blind, training-free denoiser — no installation, no Python, no noise profiles. Drag & drop your files onto the exe.

ZIP Input → Output Size
GALOSH_RAW_win64.zip DNG → denoised DNG 83 MB
GALOSH_YUV_win64.zip sRGB PNG → denoised PNG 39 MB

Usage

  • Drag & drop DNG/PNG files onto galosh_raw.exe / galosh_yuv.exe (defaults l=1 c=1), or:
galosh_raw.exe -l 0.8 -c 1.2 photo.dng
galosh_raw.exe --gpu photo.dng          (OpenCL fast path)
galosh_yuv.exe -l 1 -c 1.2 photo.png
  • Output is written next to the original as <name>_GALOSH_l<L>_c<C>.dng/.png; the original is never modified.
  • -l = luminance strength (lower to keep grain), -c = chrominance strength (raise if color blotches remain).

Highlights

  • Fully blind: per-image Poisson–Gaussian noise fit — no noise profile, no training data, any camera.
  • Any 2×2 Bayer CFA DNG (RGGB/GRBG/GBRG/BGGR); convert native raws (NEF/CR3/ARW…) to DNG first. X-Trans / monochrome / linear DNGs are rejected with a clear error.
  • Metadata fully copied from the original via bundled ExifTool — EXIF, GPS, MakerNotes, XMP, ICC, and the DNG color-calibration tags (ColorMatrix1/2, dual-illuminant calibration, AsShotNeutral, lens opcodes), so raw converters render the same colors as the original. Deliberately not copied: NoiseProfile (no longer true after denoising) and LinearizationTable (output is already linearized).
  • PNG: RGB / RGBA / grayscale, alpha preserved untouched; 16-bit inputs are processed at 8-bit precision (with a notice).
