How to adjust and combine multiple lower quality photos into one better using FOSS?
- by Vi
I have multiple noisy photos (caputed without tripod) that needs to be adjusted (moved/rotated) and averaged.
How it's better to do it in Linux with FOSS console-based programs?
Current way is something like:
mplayer mf://*.JPG -vo yuv4mpeg:file=qqq.yuv
transcode -i qqq.yuv -y null -J stabilize=maxshift=500:fieldsize=100:fieldnum=6:stepsize=50:shakiness=10
transcode -i qqq.yuv -J transform=smoothing=100000:sharpen=0:optzoom=0 -y raw -o www.yuv
mplayer www.yuv -vo pnm
gm convert -average 0*.ppm q.ppm
i.e.:
Convert photos to video
Apply Transcode's "Stabilize" filter
Convert the video back to images
Average the images.
It works, but bad: photos still not perfectly adjusted and the whole sequence is very slow.
What is better way of doing it?
