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

Figure 5

Procedure to identify the segmented stem path. The gray-scale wireframes at (a) and (b) represent, respectively, the distance between the stem start and top node: the darker is the skeleton path, and the smaller is the distance, in pixels, between these extremity points and the other skeleton points. The sum of these two outputs is illustrated in (c), and its regional minimum is shown in (d), which can be interpreted as the stem skeleton and final path (image scales 2/5).
