一种基于级联神经网络的飞机检测方法
1.Introduction
Airplanedetectiontechnologyisanimportantcomponentofmanyapplications,frommilitarysurveillancetociviliansafety.Detectingaplaneeffectivelyandefficientlycanbeasurprisinglydifficulttask,especiallywhentheplaneisflyingathighspeedorlowaltitude.Thedetectionofaircraftinremoteareasorinadverseweatherconditionscanbeespeciallychallenging,astheusualmethodsofdetectingplanesmaynotalwayswork.
Traditionalmethodsofairplanedetectionhaveinvolvedusingspecialequipmentsuchasradarorsonar.However,thesemethodsdonotworkwellincertaincontexts,suchasinurbanenvironmentswheretheremaybealotofbackgroundnoise.Inaddition,suchmethodsmaybeexpensiveandrequirealotofequipment.
Recently,machinelearninganddeeplearningalgorithmshaveemergedaspowerfulandeffectivetoolsfordetectingairplanes.Inparticular,theuseofconvolutionalneuralnetworks(CNNs)hasfoundgreatsuccessinobjectdetectiontasks,includingdetectingairplanes.
