Description

Visualizes the stroke region of a character-like binary image using the result from cog_stroke(). Optionally overlays crosshair lines at the computed center of gravity (COG) position.

Usage

draw_stroke(lst, show_cog = TRUE, plot_image = TRUE)

Value

An object of class cimg representing the stroke image (with or without COG lines), suitable for plotting or further manipulation.

Arguments

lst

A list returned by cog_stroke, containing stroke pixel data and computed statistics.

show_cog
