Logical Operations - Or

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

plantcv.logical_or(bin_img1, bin_img2)

returns 'or' image

  • Parameters:

    • bin_img1 - Binary image data to be compared to bin_img2.
    • bin_img2 - Binary image data to be compared to bin_img1.
  • 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

# Set global debug behavior to None (default), "print" (to file), 
# or "plot" (Jupyter Notebooks or X11)
pcv.params.debug = "plot"

# Combine two images that have had different thresholds applied to them.
# For logical 'or' operation object pixel in either image object 
# will be included in 'or' image.
ab = pcv.logical_or(maskeda_thresh, maskedb_thresh)
