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:
