Edge effect compensation for citrus canker lesion detection due to light source variation – a hyperspectral imaging application CIGR Journal
Niphadkar, Nikhil P.; Burks, Thomas F.; Qin, Jianwei; Ritenour, Mark.
The spread of citrus canker has become one of the most important challenges faced by Florida Fresh Market citrus is affecting the export of citrus fruits to several international markets including European countries.  Previous studies have shown that automated detection systems can help detect citrus canker infected fruit and could assist in eliminating the detected fruit from shipment to closed markets.  Most automated detection systems use some form of machine vision with artificial light sources.  However, when capturing images of spherical objects, non-uniform illumination results in an edge blackening effect resulting in higher misclassification rate.  The basic objective of this research was to implement a compensation algorithm to eliminate the edge...
