Adjust skeleton poses due to filtered depth

[pattacini]

Once we have the skeletons retrieved from the filtered depth, we need to compensate for the incorrect depth by applying a kind of unwarping in order to adjust the skeleton pose.

[pattacini]

It came out that with the following parameters, the filtered depth gives us skeletons with the correct metrics:

[depth]
enable                      true
kernel-size                 10
iterations                  5
min-distance                0.5
max-distance                10.0

Thus, @vvasco could you please try out the options above within TUG experiments and report here any findings?

With the following parameters:

[depth]
enable                      true
kernel-size                 4
iterations                  3
min-distance                0.5
max-distance                10.0

I obtained the following result:

The ankles look reasonably close to the lines when I stand on them. I checked the metric I use for line crossing and it works out with these parameters.

Awesome! Let's go this way then ✨ Could you please put those parameters in master for the TUG?

[vvasco]

Sure!

Soon afterward, please close this issue with a pointer to the commit hash.
