Mars Raw Image Processing Options

[Kevin Gill]

I wanted to let you know of a project that I've been poking at for the past year. In an effort to streamline my own processing of raw MSL/Perseverance/InSight imaging, I created Mars Raw Utils (boring name, I know...). It has utilities for batch downloading images from the raw image websites and ILT/RAD/etc calibration. Calibration includes decompanding/LUT, debayer, flat fielding, blemish repair/inpainting, color correction, and hot pixel correction. I also made utilities for creating dust devil gifs, Photoshop/GIMP-like levels adjustments, cropping, focus merging, inpainting, and determining current mission date/time/sol. Calibration files are included in the installation and easily modified and/or replaced.

This is all done with the acknowledgment that the raw images are compressed and otherwise modified from the full mission data products so calibration is only a 'best effort' process and full PDS-quality output is not expected. The output is formatted with the expectation that you'll want to do additional processing in Gimp, Photoshop, etc.

It's all command-line driven, multi-platform, open source, and written in Rust.

Here's the project homepage on GitHub: https://github.com/kmgill/mars-raw-utils

And an overview/quickstart: https://github.com/kmgill/mars-raw-utils/wiki

I'm implementing new calibration steps as I get to them, though my latest efforts have been on implementing full support for CAHV/OR/E camera models and compositing.
