ft_extract compiles
rough framework for ft_extract is finished. data is loaded from pgm, fouriertransformed and exported as ics file with complex elements. now i have to check for bugs
width and height seem to work for ics export, now i have to test 3d export
running it on 161 images of camera 2 takes 7 seconds and produces 17Mb complex float output
i'm not sure if it actually uses several processors

extract exposure time from filename
in a few of the images there are errors. i don't know why. perhaps the camera data stream is broken?

note how much compression is possible using zip on the complex float data
limit the exposure time
start scan for weekend
