can we add please dumbbell and fiber (two-point) tracking?

[alexlib]

I'd like to open this is a new project and together implement the dumbbell calibration and fiber tracking - both are built on the two-point object ideas

dumbbell calibration or sometimes called wand calibration, is available in OpenPTV

Hi Alex, Ron! I am actually working with Eric, a student in our group (in cc) to implement the fiber tracking module in Ron’s new code. However we are trying to avoid the end points tracking and do “epipolar planes” instead, in order to improve the resolution in terms of the fiber orientation.. for this reason I think that the fiber tracking module is not very suitable for doing Dumbell calibration. Nevertheless I would really like to implement dumbbell calibration in a separate module, because I’ll need it in the next future, so I’m very happy to help! Let’s talk about this soon.

Great to hear. So we shall split into two separate projects:
dumbbell calibration
fiber tracking

Is it possible to get the "old" fiber, two-point tracker - it shall be useful for the dumbbell branch as well?

Unfortunately the old way I was tracking fibers was just tracking the two ends with the PTV software, nothing more.. the intriguing part was the fiber fabrication, where I was tagging the edges with a fluorescent dye. I was selecting in post processing the point couples in 3d at the same distance of the fiber length as one does to build up a structure function. Do you think that this post processing is of any usefulness? Best, Stefano Brizzolara Il giorno 9 mag 2022, alle ore 19:20, Alex Liberzon ***@***.***> ha scritto:  Hi Alex, Ron!

[alexlib]

this is precisely the dumbbell process :)

Hi,

The dumbell would be a great extension! Shall we make a zoom to discuss how to implement this?

[alexlib]

Yes let's do it

I opened a branch on my fork and started some templating.
