Visualize object sizes

This function plots separate objects as different colors and annotates the largest objects with their respective sizes.

plantcv.visualize.obj_sizes(img, mask, num_objects=100)

returns plotting_img

  • Parameters:

    • img - RGB or grayscale image data for plotting annotations.
    • mask - Binary mask made from selected contours.
    • num_objects - Optional parameter to limit the number of objects that will get annotated, default num_objects=100).
  • Context:

    • Used to annotate object sizes in a binary mask. This visualization aims to streamline the workflow building process, especially while deciding the size threshold for a fill step.
  • Example use:
    • Below

Original image:


Binary mask:


from plantcv import plantcv as pcv


plotting_img = pcv.visualize.obj_sizes(img=rgb_img, mask=mask, num_objects=27)
