Enable AUPRO (Per Region Overlap) metric to support mask

[triet1102]

Hello, I am currently using AUPRO to evaluate anomaly localization performance and it seems to be that we are not able to filter out points when calculate the metric?

I am asking if we can add support for masking to filter out unnecessary points?
A workaround that I am doing is

• create a wrapper class for AUPRO
• override the init class which adds inspection_mask parameter
• filter out unnecessary points right after the connected component analysis https://github.com/openvinotoolkit/anomalib/blob/c92fb520d25911c5864ee251e4492348b7cc66c7/src/anomalib/utils/metrics/aupro.py#L87-L94

Thanks in advance

I guess you could split/refactor the _compute function into two separate perform_cca and compute_pro functions. This would give you the ability to modify preds/cca/target based on your masking without forcing the need to support and test this in anomalib.

OK thanks @ORippler , I'll wait for the verdict before proposing a PR for that.

Thanks for the reminder @ORippler! I've missed this.

Splitting _compute to perform_cca and compute_pro functions sounds good to me.

Closing this as it has already been implemented.
