PeakDetect

PeakDetect[list] gives a binary list in which 1s correspond to peak positions in list.

• PeakDetect[list, σ] detects peaks that survive Gaussian blurring up to scale σ.
• PeakDetect[list, σ, s] detects peaks with minimum sharpness s.
• PeakDetect[list, σ, s, t] detects only peaks with values greater than t.
• PeakDetect[list, σ, {s, σs}, {t, σt}] uses different scales for thresholding sharpness and value.

Examples

data = {0, 1, 3, 5, 3, 1, 0, 2, 4, 2, 0};
PeakDetect[data]
(* {0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0} *)
