Automated Counting of Rice Planthoppers in Paddy Fields Based on Image Processing

open access: yesJournal of Integrative Agriculture, 2014
A quantitative survey of rice planthoppers in paddy fields is important to assess the population density and make forecasting decisions. Manual rice planthopper survey methods in paddy fields are time-consuming, fatiguing and tedious.
