Effect of plant canopy shape and flowers on plant count accuracy using remote sensing imagery CIGR Journal
Leiva, Josue Nahun; Robbins, J.; Saraswat, D.; She, Y.; Ehsani, R..
Separate experiments were conducted to evaluate the effect of plant canopy shape and presence of flowers on counting accuracy of container-grown plants.  Images were taken at 12 m above the ground.  Two species of juniper (Juniperus chinensis L. ‘Sea Green’ and Juniperus horizontalis Moench ‘Plumosa Compacta’) were selected to evaluate plant shape and Coral Drift ® rose (Rosa sp. ‘Meidrifora’) was used to evaluate the presence of flowers on plant count.  Counting algorithms were trained using Feature Analyst (FA).  Total counting error, false positives and unidentified plants were reported. There was no difference between all variables measured when an algorithm trained with an image displaying regular or irregular plant canopy shape was applied to images...
