Google Cloud Vision API offers extremely potent machine learning models that are pre-trained through REST and RPC API's. This is used to quickly identify and classify a class from millions of predefined categories. You could put any object, printed or handwritten text, faces, images, etc. to instantly detect using the powerful machine learning algorithms. If you are aspiring to get into the cloud computing industry through GCP, I would recommend you to check out the GCP certification course from Intellipaat.
