Auto-Segment Foot Regions from Pressure Data — pr_mask_foot

For platform recordings where foot regions must be detected from the raw pressure matrix. Uses the maximum pressure picture (MPP) to identify the foot outline, then segments into anatomical regions based on proportional geometry.

Usage

pr_mask_foot_auto(trial, n_regions = 7L, threshold = 1)

Arguments

trial: A pr_trial object from a pressure platform recording.
n_regions: Integer. 7 (default, full segmentation into heel, midfoot, met1, met2-3, met4-5, hallux, lesser toes) or 3 (heel/midfoot/forefoot).
threshold: Numeric. Minimum pressure (kPa) to consider a sensor loaded. Default 1.0.

Value

Named list of pr_mask objects.
