Multiple peoples body part IDs

[ymohamed08]

If multiple bodies are detected, the subset seems to increase, which is normal, but the ID for each body part changes. For example, the left eye has the ID of 14 but for three skeletons instead of IDs being multiples of 14 they are put next to each other in the subset so they become 14,15,16. So, now the right eye does not correspond to its ID anymore. Is there a way around this problem, to make all the ID corresponds to the skeleton point even if multiple people are detected.
