Hi
I have a more general question: At what point do you stop carrying about false-positives with a heuristic filter?
I have openSAFETY traces, where less then 0,2% of all displayed frames are false-positives. But I cannot finetune the heuristic anymore, or I increase the risk for getting false-negatives.
Is there a point in fine-tuning down to an ideal 0% or do you just say, a certain number of false-positives should be considered ok?
There are two approaches left for me, to further down the number, first being, that I rewrite the CRC calculation and include it in the heuristic search for frame 2. This might increase the time the dissection needs to filter. The second approach is to include a preference, and filter out certain number in a field, because they highly suggest a false-positive.
Both approaches would complicate the development of openSAFETY device, because you would no longer see false messages which might occur during development.
Has anyone got some ideas here?
regards,
Roland
