Hi,
you can do this:

NativeImageLoader loader = new NativeImageLoader(28, 28, 1);
ImagePreProcessingScaler imagePreProcessingScaler = new ImagePreProcessingScaler(0, 1);
File imageFile = new File("/home/admins/desktop/1.jpg");
INDArray indArray = loader.asMatrix(imageFile);
imagePreProcessingScaler.transform(indArray);
INDArray results = model.outputSingle(indArray);

and then inspect results and take the index of the highest value.

See here for similar examples:
