Question about using Gaussian filter on anomaly map

[Jasonlee1995]

I enjoyed ur paper and visit ur repo.

First of all, I'm new in this anomaly detection task.

https://github.com/caoyunkang/AdaCLIP/blob/main/method/trainer.py#L193-L196

What I don't understand is that anomaly map is Gaussian filtered before calculating metrics.

I think controlling this parameter may change the results.
(using Gaussian filter or not, if use then what sigma to use, ...)

Is there specific reason for this? or is it common in this field?

Thank you for your interest! In this field, it is common practice to use a Gaussian filter. To ensure fair comparisons, we typically use the same Gaussian filter parameters.
