plantcv.roi.from_binary_image(img, bin_img)

returns roi_contour, roi_hierarchy

  • Parameters:
    • img - An RGB or grayscale image to plot the ROI on in debug mode.
    • bin_img - Binary image. The ROI contour will be identified from this image.
  • Context:
    • Used to define a region of interest in the image.

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

roi_contour, roi_hierarchy = pcv.roi.from_binary_image(img=rgb_img, bin_img=bin_img)
