machinevisiontoolbox.Image.blobs

Image.blobs(**kwargs)

Find and describe blobs in image

Returns:

blobs in the image

Return type:

Blobs

Find all blobs in the image and return an object that contains geometric information about them. The object behaves like a list so it can be indexed and sliced.

Example:

>>> from machinevisiontoolbox import Image
>>> im = Image.Read('shark2.png')
>>> blobs = im.blobs()
>>> type(blobs)
<class 'machinevisiontoolbox.ImageBlobs.Blobs'>
>>> len(blobs)
2
>>> print(blobs)
