Blobs.plot_aligned_box

Blobs.plot_aligned_box(*args, **kwargs: Any) → None

Plot aligned rectangles of blobs using Matplotlib

Parameters:

kwargs – line style parameters passed to plot

Compute the minimal enclosing box whose sides are parallel to the axes of the equivalent ellipse. Return a list of vertices (not closed) and a list of box centroids. Highlights the perimeter of a blob or blobs on the current plot.

Example:

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