How does the TOMHT handles the input of detectable branchID's?

Hi again,

First of all thanks for all the support I have gotten so far. I have another question. The tomht tracker provides the option to pass on a list of branch ID's that will be considered detectable in the next update. I was wondering, how does the TOMHT tracker handle this input? Does it simply predicts these branches and handles the score differently for these branches?

Kind regards,

Joost

Hi Joost,

Happy to help.

For your question: the way the trackerTOMHT uses the detectableBranchIDs is that it uses the probability of detection of the detectable branches (or, if not provided in the second column of the input, the tracker PD) when calculating their score after a miss. For undetectable branches, PD is zero, so the score does not decrease. This allows you to keep undetectable or poorly detectable branches for a larger number of updates relative to not using that.

The tracker does not use it in the association. So, if a certain branch ID is considered undetected or poorly detected, but is assigned to a detection after all, the tracker allows the assignment to happen.
