Google has released the TensorFlow Object Detection API which provides access to an open source framework for constructing, training and deploying object detection models. The API provides access to Google's in-house object detection system, and includes a selection of trainable detection models.
The stakes for Machine Learning APIs are increasing by the day. Major vendors are making moves towards releasing ML platform APIs. One such release is the Cloud Natural Language API, an API from Google that provides devs the ability to investigate the structure and meaning of text via REST APIs.
