Blobs.plot_perimeter

Blobs.plot_perimeter(*args, show: str = 'full', epsilon: int | None = None, clockwise: bool = True, **kwargs: Any) → None

Plot the perimeter of blobs using Matplotlib

Parameters:

• show (str) – type of perimeter to plot, “full” (default), “approx” or “hull”

• epsilon (int (only for show="approx")) – maximum distance between the original curve and its approximation, default is exact contour

• clockwise (bool (only for show="hull")) – direction of travel for computing the hull, defaults to clockwise

• kwargs – line style parameters passed to plot

Plots the perimeter of blob or blobs on the current Matplotlib axes.

Example:

>>> from machinevisiontoolbox import Image
>>> im = Image.Read("sharks.png")
>>> blobs = im.blobs()
>>> blob.plot_perimeter() # perimeters for all blobs, different colors
>>>
>>> blobs[0].plot_perimeter("c--") # cyan dashed line
>>> blobs[1].plot_perimeter(color="cyan", linestyle="--") # cyan dashed line
>>> blobs[2].plot_perimeter(color="red")
>>> blobs[3].plot_perimeter(show="hull", color="orange", linewidth=3)
