Sky-canopy border length, exposure and thresholding influence accuracy of hemispherical photography for complex plant canopies

Abstract Background Hemispherical photography (HP) is a popular method to estimate canopy structure and understorey light environment, which analyses photographs acquired with wide view-angle lens (i.e. fisheye lens). To increase HP accuracy, the approaches of most previous studies were to increase...
