Customized integration and adaptations

For device integration with known hardware we can optimize our algorithms for best performance depending on what compute and sensors you are open to. For example, we can optimize the Nexus solution for a specific RGB camera, or adjust the Nexus algorithm to work for your choice of off the shelf NIR sensor. We can integrate to run on an SoC instead of host compute for minimal latency.

If you are looking for a different OS or a different CPU architecture, let us know what you need and we will help you out.
