API Reference

This section covers the autogenerated API documentation for HeartCV. For more examples and information, refer to the relevant guides in the User Guide.

Localisation

downsample(frames, binsize)	Downsample a sequence of frames at a given binsize for Energy Proxy Trait calculation.
epts(frames, fs[, binsize])	Compute the energy proxy traits for a mean pixel value grid.
spectral_map(epts, frequencies)	Create a heatmap based on the spectral energy in the supplied energy proxy traits (EPTs)
identify_frequencies(video, epts[, rotate, ...])	Launch a user interface to identify frequencies of interest in the supplied energy proxy traits.
detect_largest(map)	Detect the largest polygon in a heatmap produced by spectral_map.
segment(frames, roi[, invert])	Segment to the supplied ROI.

Peak detection

find_peaks(x[, plot])

Python implementation of automatic multiscale peak detection (AMPD).

Quantification of cardiac traits

bpm(num_peaks, sample_length, fs)	Calculate beats per minute based on detected peaks.
b2b_intervals(peaks, fs)	Calculate beat to beat intervals based on peaks detected.
stats(peaks, sample_length, fs[, windows])	Calculate cardiac statistics for the peaks detected.

Utilities

minmax_scale(vals)

Convenience function for performing min/max normalization.
