Calculate a peak plantar-pressure map

Calculate a peak plantar-pressure map

Usage

peakPressure(pm, contact_threshold = 0)

Arguments

pm

A pressure_movie.

contact_threshold

Pressure threshold in kPa. Cells must exceed this threshold to count toward contact area and mean pressure.

Value

A numeric peak-pressure matrix in kPa. Attributes contain the global peak, peak cell and frame, contact area, and mean active pressure.
