sun solar animation alignment
imgalt – Image Alignment Tool
author: GreatAttractor



Written with solar animation frame alignment in mind. Uses the phase correlation method to detect translations of an image sequence, which can be widely varying, the images severely cropped – exactly what one gets after a few hour solar session with telescope buffeted by wind, drift due to imperfect polar alignment and lack of manual correction in time etc.

imgalt.zip: Windows program
imgalt-src.zip: source code (requires Boost libraries; tested with GCC/G++ on Linux & Windows and with MS C++)

Binaries and source code may be freely distributed and used for any purpose. See the README file for details on usage and building.

 
QUICK START

Imgalt is a "console application" (it has no graphical interface). Running
from a console (a.k.a. "command prompt") is recommended, but not
necessary. This method will work as well:
  • Unzip the imgalt.zip, say, to folder "imgalt" on your Desktop.
  • Copy all the files you want to align (in BMP or TIFF format) to the same "imgalt" folder.
  • Run imgalt.exe; it will open a window which displays progress.
  • After a few moments you will have new, aligned files (with names ending in "_aligned"), also in the same "imgalt" folder.
More information in the README file.
