EstimatedBackground

EstimatedBackground[data] estimates the background of data.

EstimatedBackground[data, σ] tries to preserve peaks up to scale σ.

Examples

Estimate background from noisy data:

data = Table[Sin[x] + RandomReal[0.1], {x, 0, 10, 0.1}];
EstimatedBackground[data]

Preserve peaks with a specific scale:

EstimatedBackground[data, 5]
