SIFT | Point-Positions

[Rainer M. Engel]

Hi, I'm not sure if there is a way to get the positions of corresponding
feature points calculated by SIFT as floating values since the positions
derived from the multi-point selection afterwards is rounded/fixed to
integer values.

Otherwise just a thought..

Regards,
Rainer

Hi Rainer,

the implementation stems from when ImageJ had no floating point
precision in PointRoi.  I'll adjust the plugin to use floating points
some time soon...

Best,
Stephan
