Modification of the combined association cost: lambda #295

Open cesc47 opened 2 years ago

cesc47 commented 2 years ago

Hi,

Is there a way to modify the gate that gives more weight to the appearance information (from re-id network) instead of motion based model (kalman)? I tried on modifying the _gatingthreshold from the _gate_costmatrix function in linear_assignment.py but my results are very simmilar.

In other words, where is in the code the lambda parameter that appears in the first paragraph of the third page of the paper?

I think that I am missing something here.

Thanks in advance for the help.

Check out issue #112. The author of the code has responded in that issue, saying the final implementation has no lambda parameter to modify. There is however someone else (who replied in that issue) saying they implemented the lambda parameter.
