There is a tag for background-subtraction, with only 20 questions. Although this term is common in image processing, several questions have been asked recently for signals or time series.
I would like to suggest the creation of a specific tag, with synonyms as many terms are used: baseline (potentially misleading), trend, drift, wander.
- Do you feel (as I do) this is necessary?
- What could be the most appropriate main tag name?
