Plot a sequence of skeleton frames

Creates a multi-panel faceted plot showing the skeleton at several frames.

Usage

plotSkeletonSequence(
  pe,
  skeleton,
  frames,
  plane = c("sagittal", "frontal", "transverse"),
  ncol = 3,
  show_labels = FALSE,
  show_confidence = FALSE,
  point_size = 2,
  segment_color = "gray40",
  title = NULL
)

Arguments

pe

A PhysioExperiment object with position_x, position_y, and position_z assays (columns named by keypoint label).

skeleton

A SkeletonModel object whose keypoint labels match column names in the position assays.

frames

Integer vector of frame indices to plot.

plane

Anatomical plane for projection: "sagittal" (drop X), "frontal" (drop Y), or "transverse" (drop Z).

ncol

Number of columns in the faceted layout (default 3).

show_labels

Logical; annotate markers with their labels.

show_confidence

Logical; color markers by confidence if a confidence assay is present.

point_size

Marker point size (default 3).

segment_color

Color for bone segments (default "gray40").

title

Plot title. If NULL, auto-generated.

Value

A ggplot object with facets.

Examples

if (FALSE) { # \dontrun{
pe <- readOpenPose("frames/", model = "BODY_25")
sk <- define_skeleton("BODY_25")
plotSkeletonSequence(pe, sk, frames = c(1, 10, 20), ncol = 3)
} # }
