Projects:-

1)ImageProcessing&Classification-CNN(Python)

Objective:-ToCreateamodelwhichcanidentifytheInputImagesandClassifythem intospecific Class/Category.

Analysis:-

WehavecollectedagoodnumberofimagesofdifferentCats&Dogs(10,000images).Webuilta CNNmodelbasedonourrequirements.ThenCNNmodelistrainedontheinputimagesusing KERASlibrary.Thetrainedmodelistestedwithfewsamplesofimages,whichhasdetectedthe ClassoftheImages.

Responsibilities:-

Importedessentialfunctionsfrom KerasLibrary.PerformedtheinitializationofCNNmodel& Added1stConvolutionLayertoourmodel.AddedMax-PoolingtoCNNModel,Performed FlatteningandthencreatedaFull-ConnectionbetweenInputandOutput.
