Effect of spatial resolution of hyperspectral information on sensitivity of sensor for the detection of Cercospora leaf spot symptoms. Cubic convolution was used for spectral resampling of the original spatial resolution of 0.19 mm (79 × 87 pixels covering an area of 289 mm2) to simulate resolutions of 0.8 mm (20 × 22 pixels), 3.1 mm (5 × 6 pixels) and 17 mm (1 pixel), respectively.
