topologicalpeakdetection

License: MIT

This crate finds peaks inside of 1-D signals (vectors of PartialOrd satisfying types) using topological persistance.

What it does:

• Returns peaks and regions in a 1-D signal.
• Should work on all types which can be sorted.

What it doesn't do:

• it doesn't tolerance peaks, maybe it should maybe it shouldn't.
• it doesn't apply to 2 or higher dimensions. It easily can, but, currently, it doesn't.
• it does not merge homology's for birth/death analysis. It easily could.

Here's a simple example:

Examples

rust let tst_vec:Vec<f32> = (0..6001) .map(|x| ((x as f32 / 1000_f32) * PI).sin()) .collect(); let homologies = find_homologies(&tst_vec); let x = get_peaks(&homologies); // x == [500, 2500, 4500, 6000]
