Hi imagej gurus,
I'm rather new to imagej and fiji however it has already been proven to be
a very useful platform for me as such I would like to continue using fiji /
imagej in a proof of concept registration exercise. But, I need some advice
on getting to certain data.
About the image vision problem: I want to align webcam images and
compensate for image shifts by registering images in a sliding window
-through a stack- approach. The reason for doing this with a sliding window
approach is that features are not stable due to changes in vegetation state
(leaf on / leaf off).
Within this context I would like to extract feature statistics from the
'Extract SIFT Correspondences' plugin. Sadly, although I can read the
features in to bUnwarpJ I cannot access the statistics as produced by the
SIFT procedure as there is no text output. I need access to these
statistics as they are a marker for bad images (snow on the lens, mist,
other reasons why features could not be detected). Using these statistics I
can kick out, 'bad' days and only register the 'good' days.
One option would be to scrobble the output to the terminal output for any
log data, but this seems cumbersome and non robust. Is there another way to
use standard fiji macro language and access this log data? And if not are
these statistics on SIFT analysis readable in some other setup (jython /
java calling of the classes).
Any help or input on how to tackle this is appreciated.
Cheers,
Koen
