 * Run the frame classification demo, e.g. ```./imagenet-camera```.  What is the framerate you are getting? Try [other networks](https://github.com/dusty-nv/jetson-inference/blob/master/docs/imagenet-camera.md)
 * Run the object detection demo, e.g. ```./detectnet-camera```. What is the framerate now?  Experiment with [other networks](https://github.com/dusty-nv/jetson-inference/blob/master/docs/detectnet-camera-2.md)
 * Try to image segmentation demo as well: ```./segnet-camera``` Experiment with [other networks](https://github.com/dusty-nv/jetson-inference/blob/master/docs/segnet-console.md)
