Using digital image processing for counting whiteflies on soybean leaves

다국어 초록 (Multilingual Abstract)

This paper presents a new system, based on digital image processing, to quantify whiteflies on soybean leaves.
This approach allows counting to be fully automated, considerably speeding up the process in comparisonwith the manual approach. The proposed algorithm is capable of detecting and quantifying not only adultwhiteflies,but also specimens in the nymph stage. A complete performance evaluation is presented, with emphasis onthe conditions and situations for which the algorithm succeeds, and also on the circumstances that need furtherwork. Although this proposal was entirely developed using soybean leaves, it can be easily extended to otherkinds of crops with little or no changes in the algorithm. The systememploys only widely used image processingoperations, so it can be easily implemented in any image processing software package.
