draw_potential: Visualize Potential-Based Center of Gravity (COG) and Potential Field

Description

Visualizes the normalized potential field and center of gravity (COG) computed by cog_potential. Each pixel's potential is shown as grayscale intensity, where darker pixels indicate higher potential. Optionally overlays crosshair lines at the computed COG to indicate its position.

Usage

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

Value

An object of class cimg representing the potential field image, optionally overlaid with COG crosshair lines.

Arguments

lst

A list returned by cog_potential, containing a data frame of normalized potentials and computed statistics.

show_cog

Logical. If TRUE (default), draws horizontal and vertical red lines through the COG.

plot_image

Logical. If TRUE (default), plots the generated image. If FALSE, returns the image object without displaying it.
