solar eclipse photo processing

if you want to make an animation or gif from the image files ( image to video )
1. align and crop ( optional )

2. use ImPPG to align

use PIPP to output as animation

PIPP setting:

PS: PIPP also has  center and crop feature, but it doesn't work for me.Only roughly 3 in 4 images are aligned properly

ImPPG download

PIPP download

alternatives:

- ImageMagick instead of PIPP

using free / trial softwares:
-  : MATLAB + 'minboundcircle' written by John D'Errico, github

Which is in turn using convex hull

- OpenCV + Lucas-Kande method (optical flow), using eg python

-  互相关 + FFT in numPy

R + astrolib



using paid softwares:
PixInsight, FFT registration script
