Compute peak prominence on 2d array using contour method using numpy and
matplotlib
The prominence of a local maximum (peak) is defined as
the height of the peak's summit above the lowest contour line encircling it but containing no higher summit.
See wikipedia for more details.
This module takes a surface in R3 defined by 2D arrays of X, Y and Z, and use enclosing contours to find local maxima and their prominences.
Optionally, peaks with small prominence or area can be filtered out.
See a toy example below:
