Filters out dark noise from an image.

plantcv.closing(gray_img, kernel=None)

returns filtered_img

• Parameters:
  • gray_img - Grayscale or binary image data
  • kernel - Optional neighborhood, expressed as an array of 1's and 0's. If None, use cross-shaped structuring element.
• Context:
  • Used to reduce image noise, specifically small dark spots (i.e. "pepper").
• Example use:
  • See below

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 = "print"

# Apply closing

filtered_img = pcv.closing(gray_img)
