Logical Operations - And

Join two images using the bitwise AND operator. Images must be the same size. This is a wrapper for the Opencv Function bitwise_and.

logical_and(img1, img2, device, debug=None)

returns device, 'and' image

  • Parameters:
    • img1 - image object 1.
    • img2 - image object 2.
    • device - Counter for image processing steps
    • debug - None, "print", or "plot". Print = save to file, Plot = print to screen. Default = None
  • Context:
    • Used to combine to images. Very useful when combining image channels that have been thresholded seperately.
  • Example use:

Input binary image 1

Input binary image 2

from plantcv import plantcv as pcv

# Combine two images that have had different thresholds applied to them.
# For logical 'and' operation object pixel must be in both images to be included in 'and' image.
device, and_image = pcv.logical_and(s_threshold, b_threshold, device, debug="print")
