Combine objects together for downstream analysis, usually done after object filtering.
object_composition(img, contours, hierarchy, device, debug=None)
returns device, grouped object, image mask
- contours- object list
- device- device number. Used to count steps in the pipeline
- debug - None, "print", or "plot". Print = save to file, Plot = print to screen. Default = None
- This function combines objects together. This is important for downstream analysis of shape characteristics, if plant objects are not combined then one plant can appear to be many different objects.
- Example use:
import plantcv as pcv # Combine objects so downstream analysis can be run on a single plant object device, obj, mask = pcv.object_composition(img, roi_objects, hierarchy, device, debug="print")
