Unreleased ¶

ColorMagnifier: Eulerian colour magnification (Wu et al. 2012) with Gaussian pyramid, ideal and Butterworth bandpass filters, streaming support.
MotionMagnifier: Eulerian motion magnification (Wu et al. 2012) with Laplacian pyramid.
PhaseMagnifier: Phase-based motion magnification (Wadhwa et al. 2013) with analytic steerable pyramid, circular phase wrapping, large-motion attenuation (Fig. 11).
Notch filter support in all three magnifiers (ideal FFT mask + IIR cascade) for removing light flicker (50/60 Hz) or other periodic artefacts.
Nyquist validation with clear error messages when requested frequencies exceed fps / 2.
GPU-accelerated video I/O via torchcodec (optional fast-io extra; Linux/Windows via pixi).
CLI (pyevm color / motion / phase / info / dashboard) powered by Typer.
Interactive Streamlit dashboard (pyevm dashboard).
Automatic device selection: CUDA → MPS → CPU, overridable with --device.
PyPI distribution name pyeulervid; import as pyevm; CLI as pyevm.
