Validate/improve sub-pixel accuracy

Open strasdat opened this issue 13 years ago • 0 comments

At the moment there is a method for sub-pixel accuracy at the moment, which - however - is deactivated. It is a simple direct method (Lukas Kanade tracking) using 1 iteration of Gauss Newton.

There are a few things to do:

  • Test whether everything works correct.
  • Try out ESM and see whether it pays off.
  • We should not include accept updates < 1 pixel.
  • Shall we test whether the update actually reduces the error (either using LM or line search)?
