Abstract:Toaddressthe insufficientand imbalancedsample sizes of cottonleaf mitedamage images at different severity levels,reducedatacollectioncosts,andenhancethequalityanddiversityofimagesgeneratedbygenerativeadversarialnetworks,thisstudyproposedanimprovedDCGAN-baseddataaugmentationmethodforcoton leaf mitedamageimages.Basedon theoriginalmodel,ategorylabelswereintroducedtoeableargetedgenerationofimagesfordiferentdamagelevels,ectively resolvingtheissueofclassimbalance.Thetraditional directconnectionstructurewasreplacedwitharesidualstructuretoenhance the model’sabilty to leam complex mapping relationships,avoid gradient vanishing problems,and improvethequalityof generatedimages.Aditionally,theconvolutional blockatentionmodule(CBAM)wasembedded intheconvolutionallayers to strengthenthe model’s capacity to extract key featuresof cottonleafmitedamageimages,further enhancingthequality anddiversityofgenerated images.Lastly,theWasserstein distancewith gradient penaltywas employed as the loss function,avoiding the problem of mode collapse and enhancing thetraining stability ofthe model. The improved DCGAN
