The Classify method

Now that we understand a little bit about CNNs, we are ready to put this knowledge into practice. We are going to create an asynchronous classification method. TensorFlow can work with a number of formats when it needs to detect images, so we are going to generalize our method to only accept the appropriate types:

public async Classify(image: tf.Tensor3D | ImageData | HTMLImageElement |   HTMLCanvasElement | HTMLVideoElement):    Promise<TensorInformation[] | null> {}

Only one of these types is specific to TensorFlow—the Tensor3D type. All the other types are standard DOM types, so this can be easily consumed in a web page without having to jump through numerous hoops to convert the image into a suitable format.

We haven't ...
