StagedFilters.jl - Lovingly handcrafted metaprogrammed code for all your DSP needs.
This package implements a staged-programming approach for a highly specialized version of a Savitzky-Golay filter. It is a generalized, performant algorithm of rolling/moving functions, such as a
Many people contributed to the eventual development of this code:
- Jiahao Chen, Matt Bauman and others for the original implementation
- Stefan Karpinski for some branch elisions
- Steven G Johnson, for help when benchmarking a PyCall code and being careful not to measure the conversion back and forth.
If you know the measurement to be missing / not be as fair as it could be, please reach out and let me know - we're trying to compare best in class implementations side by side, not cheat out. In particular, I don't know if the
savgol method I'm calling is in place or not, and would appreciate if somone could point out how to opt into that.
