smart_arrays_peaks 2.0.2

Smart Arrays Peaks #

What the package can do for you #

This package provides functions that detect peaks (maximum values) in one- or two-dimensional arrays. Peak detection (peak search, peak picking) does not simply mean finding maximum values. Data originating from measurements are often subject to noise, i.e. random small variations of the measured values. The provided algorithms therefore allow you to specify a noise value to suppress to exclude noise effects from peak search.

The major API functionalities #

class PeakPicker1D

This example will pick the positive and negative peaks in the entire array using the noise discriminator 2.0. The result contains the array indices of the found peaks.

List<int> peakIndices = PeakPicker1D.detectPeaks( array, 0, array.length, 2.0, 0.0, PeakPicker1D.PICK_POSNEG, 0);

class PeakPicker2D:

This example will pick the negative peaks in the entire array2D using the noise discriminator 2.0. The result contains the array indices (row/column pairs) of the found peaks.

List<List<int>> peakIndices = PeakPicker2D.detectPeaks( array2D, 0, array2D.length,0,array2D[0].lebngth, 2.0, 0.00, PeakPicker1D.PICK_NEG, 0);
