+# HoloLens Reprojection
+This sample project demonstrates how you can use the HoloLens LocatableCamera to project 2D image analysis results back into world space to add a visualization to the objects detected.
+
+The user snaps a photo with the front-facing web camera on HoloLens and then posts it to an inference pipeline for object detection and classification.

+
+## Setup
+
+I got started by training a custom vision classifier on http://customvision.ai. (see above for how to get started)
+
+For my sample, I create a model to detect coffee mugs and classify them.
+

+
+You will need to create a train your own model on the Custom Vision portal, or roll your own inference pipeline and integrate the reporjection components into your project.
+
+Once you publish the iteration that you're happy with, you will input that URL and the Prediction Key value into the CustomVisionServiceConfig object.
+
+![CustomVisionServiceConfig](Images/customvisionserviceconfig.jpg?raw=true)
+
+Then, it will need to be set on the SceneController component.
+
+![Set the config](Images/customvisionserviceconfig_set.jpg?raw=true)
+
+That should be all you need to do. Don't forget to setup your HoloLens project settings and then build out to Visual Studio.
