Basically, I have a 2-dimensional data set and I want to identify local peaks in the data, while ignoring "trivial" peaks. My naive algorithm first identifies every peak and valley (point of inflection change in the graph), then shaves off shallow peaks and valleys based on an arbitrary depth parameter, then returns whatever is left. This produces decent results, but, again, I'd like to know what other implementations are available.
