A lot of work has been done to automate the visual inspection of the fruits by machine vision with respect to size and color. An early detection of fruit diseases can aid in decreasing such losses and can stop further spread of diseases. Some fruit diseases also infect other areas of the tree causing diseases of twigs, leaves and branches.

For example, soybean rust (a fungal disease in soybeans) has caused a significant economic loss and just by removing 20% of the infection, the farmers may benefit with an approximately 11 million-dollar profit (Roberts et al., 2006). Fruit diseases can cause significant losses in yield and quality appeared in harvesting. Diseases in fruit cause devastating problem in economic losses and production in agricultural industry worldwide.
