Processing total solar eclipse images
🏗️ This page is a work in progress. 🏗️
This blog post will eventually include a summary of how I processed my images of the April 2024 total solar eclipse (TSE). My goal is to reproduce–at least in part–the methods of Miroslav Druckmüller, Nicolas Lefaudeux, and others using Druckmüller’s pubished methodology… but this is much easier said than done! 😅 For now, this post will simply contain a list resources I found useful.
I imagine the final process will be comprised of the following steps: (these will likely become links to separate blog posts as they are completed)
- Taking images
- Reading image files in MATLAB
- Image calibration in MATLAB
- Subpixel image registration
- Image stacking (linear HDR)
- Adaptive filtering
- And more…?
