scir-fft 0.3.5

SciR FFT: parity-first FFT/RFFT/IRFFT plus reusable 2D vision spectral kernels.
Documentation

scir-fft

Overview

  • FFT utilities for SciR with a parity-first approach. Uses fixtures generated from SciPy to validate fft, ifft, rfft, and irfft against reference outputs.
  • vision exposes reusable 2D spectral image kernels: FFT magnitude, centered frequency layout, Hann windowing, log-polar resampling, Fourier-Mellin magnitude signatures, and bin-level rotation/scale pose estimates. Stream/time wrappers remain Streamz-owned; application and Spectral-Pick callers consume these kernels rather than owning the math.

Backends

  • CPU: rustfft (complex) and realfft (real transforms).
