# ML.NET Model Builder Stop Sign Object Detection
This sample relates to the [ML.NET Model Builder Object Detection tutorial](https://docs.microsoft.com/dotnet/machine-learning/tutorials/object-detection-model-builder).
## Contents
| Project | Description |
|-----------------------------|-------------------------------------------------------------|
| `StopSignDetection` | Console app that consumes the trained model. |
| `StopSignDetectionML.Model` | Class library that contains the model and consumption code. |
The test image `test-image1.jpeg` is from [pexels](https://www.pexels.com/photo/red-stop-sign-39080/).
## Prerequisites
- Visual Studio 2019 16.6.1 or later
- .NET workload installed with ML.NET Model Builder component checked
- ML.NET Model Builder Preview Feature enabled
You can see Model Builder set up instructions in this [tutorial](https://dotnet.microsoft.com/learn/ml-dotnet/get-started-tutorial/install).
## Running the sample
You can either:
1. Follow along with the tutorial and have Model Builder generate the code for you, or
2. Clone this sample which already contains the necessary code and run the `StopSignDetection` console app to consume a trained ML.NET object detection model.
