Hand Gesture Recognition Demo using AlexNet & MATLAB

 

%Code for training:

 

clc

clear all

close all

warning off

g=alexnet;

layers=g.Layers;

layers(23)=fullyConnectedLayer(7);

layers(25)=classificationLayer;

allImages=imageDatastore('Hand Dataset','IncludeSubfolders',true, 'LabelSource','foldernames');

opts=trainingOptions('sgdm','InitialLearnRate',0.001,'MaxEpochs',20,'MiniBatchSize',64);

myNet1=trainNetwork(allImages,layers,opts);

save myNet1;

 

 

%Code for testing:
