Detecting Sorghum Plant and Head Features from Multispectral UAV Imagery
Figure 11
(a) Accuracy of sorghum heads determined by the reverse-calculated plot images compared with manually labelled images. (b) Detection results compared to labelled images. Solid yellow arrows show underestimated heads (i.e., triple heads identified as double in image set 1; double heads identified as single in set 2), and dashed arrows show missed detections of green heads in image set 3 (blue: single head; green: double head; red: triple head).
