heartcv.epts

heartcv.epts(frames, fs, binsize=1)[source]

Compute the energy proxy traits for a mean pixel value grid.

Parameters

  • frames (list or ndarray or vuba.Frames) – Sequence of frames to compute mean pixel values for.

  • fs (int or float) – Sampling frequency for video.

  • binsize – Binning resolution to downsample the supplied image frames by. Default is a binning factor of 1, i.e. no downsampling.

Returns

ept – Energy proxy traits, split into frequency and power arrays respectively.

Return type

tuple
