Blobs.plot_centroid

Blobs.plot_centroid(*args, label: bool = False, **kwargs: Any) → None

Plot the centroid of blobs using Matplotlib

Parameters:

• label (bool) – add a sequential numeric label to each point, defaults to False

• kwargs –

  other arguments passed to plot_point

  Plot the major and minor axes of a blob or blobs on the current Matplotlib axes.

If no marker style is given then it will be an overlaid “o” and “x” in blue.

Example:

>>> from machinevisiontoolbox import Image
>>> im = Image.Read("sharks.png")
>>> blobs = im.blobs()
>>> blobs.plot_centroid(label=True)  # default blue "o" and "x" with blob id for all blobs
>>>
>>> blobs[0].plot_centroid()  # default blue "o" and "x"
>>> blobs[1].plot_centroid('rd', label=True) # red diamond with label
>>> blobs[2].plot_centroid(marker="x", color="red") # red "x"
>>> blobs[3].plot_centroid(marker="P", markeredgecolor="lightsteelblue", markerfacecolor="w", fillstyle="full")
