Open source multi-platform program for focus stacking many images.
View the wiki for instructions.
Focus stacking is often a necessity when working with high-magnification pictures... Chimpstackr implements the laplacian pyramid fusion algorithm (see: Sources)
Following image stacks have been taken by me. Each image has been stacked using ChimpStackr and post-processed using darktable. Each image stack contains around 150 individual images. Every image in the stack was taken at around 4x magnification on a (slightly) wobbly rig. This should be a good test for both the stacking algorithm, and the alignment algorithm.
The post processing consists of these steps:
The alignment/stacking process for ~150 images took about three minutes on my hardware.
Clone repository
Install python requirements: pip install -r requirements.txt
Run file src/run.py
to start the program
Note: you can only build for your current platform. So for example building an AppImage on Windows is not possible natively.
AppImage: appimage-builder
Windows/MacOS: pyinstaller --icon=packaging/icons/icon_512x512.png -F -w -n ChimpStackr src/run.py
