Nonuniform Illumination Correction

Corrects for nonuniform lighting in an image.

plantcv.nonuniform_illumination(img, ksize)

returns Grayscale image after correction

  • Parameters:

    • img - RGB or grayscale image
    • ksize - Kernel size
  • Context:

    • Corrects for nonuniform illumination for situations where there is no available background image to do background subtraction. The function corrects for nonuniform lighting by creating a background image from the original by blurring with the specified kernel size.

Input image


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"

# Correct illumination in the image
corrected_img = pcv.transform.nonuniform_illumination(img=img, ksize=31)
