Now that we have loaded the image and the pre-trained network, we shall preprocess the image, feed it to the neural network to predict the class of the image.
Note::
image.img_to_array : Converts a PIL Image instance to a Numpy array.
tensorflow.keras.applications.inception_v3.preprocess_input : The images are converted from RGB to BGR, then each color channel is zero-centered with respect to the ImageNet dataset, without scaling.
tensorflow.keras.applications.inception_v3.decode_predictions : Decodes the prediction into a list of tuples (class, description, probability)
Converts the PIL image img to np array x using image.img_to_array function.
x = << your code comes here >>(img)
The model expects to be fed with an array of images. So write as follows:
x= np.array([x])
Preprocess the x using preprocess_input.
x = << your code comes here >>(x)
Predict the class probabilities of the input image x using model.predict.
preds = << your code comes here>>(x)
Decode the predictions and print the top 3 prediction probabilities as follow:
print('Predicted:', decode_predictions(preds, top=3)[0])
