 The nodes use the image recognition, object detection, and semantic segmentation DNN's from the [`jetson-inference`](https://github.com/dusty-nv/jetson-inference) library and NVIDIA [Hello AI World](https://github.com/dusty-nv/jetson-inference#hello-ai-world) tutorial, which come with several built-in pretrained networks for classification, detection, and segmentation and the ability to load customized user-trained models.
