It comes with Azure Machine Learning, a cloud service to build and deploy ML models faster. I'm looking to train a custom object detection model using Tensorflow's API. Object Detection An approach to building an object detection is to first build a classifier that can classify closely cropped images of an object. Specifically, detection is about not only finding the class of object but also localizing the extent of an object in the image. Fig 2. shows an example of such a model, where a model is trained on a dataset of closely cropped images of a car and the model predicts the probability of an image being a car. The Detect API applies tags based on the objects or living things identified in the image. Motion Detection is a technology to detect motion events within video, and is currently in free public preview. Object detection is a process for identifying a specific object in a digital image. Each domain optimizes the detector for specific types of images, as described in the following table. You should see activity in the console with images and messages being sent to the IoT Hub.
