High-Throughput Corn Image Segmentation and Trait Extraction Using Chlorophyll Fluorescence Images

Figure 4

Canopy traits extraction: extraction based on the points of interest calculated in the skeleton. First, the segmented stem and leaves were labeled; features (traits) of the labeled organs were then calculated (image scale 1/4). Skeleton with points of interests: the blue markers are the endpoints and leaf tips. The purple one is the stem start, and the cyan one is the top node, considered the end of the segmented stem. The green points are the nodes of the plant or branch points. The yellow diamond-shape marker is the center of mass of the skeleton. The angle between leaf tip and stem was calculated based on the two extremity points of the leaf, as exemplified by and (image scale 1/2).
