Hi! I want to classify seeds into four categories. With that, I trained a googlenet cnn. However, I would like to classify another set of images at once using the trained network I've made. Can anyone guide me on how to do it? Thank you so much!

Assuming that another set of images belong to the four seed categories, then no extra work is required. The trained 'GoolgeNet' can be used.

If the images are from different class(es), then ‘GoogleNet’ can be fine-tuned with data from the new classes along with the four seed classes.

Hi @Ranjeet! Yes, I want to test another set of images (with same set of classes). With that, I made a new script with this code:

function test_network(net, image)

I = imread(image);

R = imresize(I,[224, 224]);

[Label, Probability] = classify(net, R);

figure;

imshow(R)

title({char(Label),num2str(max(Probability)*100, 6)})

end

wherein net = trained Googlenet CNN which I modified. However, the code above can only classify 1 seed at a time. I would like to classify all the seeds inside a folder automatically and generate a confusion matrix using my trained Googlenet. Please guide me. Thank you!
