Jetson Xavier NX Lesson 15: Training the Face Recognition Program to Recognize People

In this video lesson we should you a simple method to train our face recognizer on larger data sets. We use the python os.walk command to step through, and train automatically on all the training images in our folder. We then show how to store our training set to our SD card using the pickle utility. This allows us to train once, and use the trained model over and over.

For your convenience, the code below is what we developed to allow training our face recognition model.

Then this is a simple program that loads the trained model, and uses it to recognize people in unknown images.

 

Jetson Xavier NX Lesson 14: Face Recognition and Identification on NVIDIA Xavier NX

In this video lesson we show you how to train the NVIDIA Jetson Xavier NX to recognize faces, and then demonstrate finding those faces in a new unknown image.  We show step by step instruction in this easy to follow tutorial. We develop two python programs. The first one simply finds the faces in an unknown image, and the second program actually identifies the known faces. For your convenience, the code is included below.

Simple face detection Python code:

This next python program will learn faces, and then recognize them in new images.

 

Jetson Xavier NX Lesson 12: Intelligent Scanning for Objects of Interest

In this Video Tutorial we show how a camera on a pan/tilt control system can be programmed to search for an object of interest, and then track it when found.  Our system has two independent camera systems, and each can track a separate item of interest independently. The code is written in python, using the OpenCV library. The video takes you through the lesson step-by-step, and then the code is included below for your convenience.

If you want to play along at home, we are using the Jetson Xavier NX, which you can pick up HERE. You will also need to of the bracket/servo kits, which you can get HERE, and then two Raspberry Pi Version two cameras, available HERE.

 

Jetson Xavier NX Lesson 11: Independently Tracking Different Objects in Different Cameras

In this video lesson we show how two Raspberry Pi cameras can independently track to different objects of interest. As a demonstration, we track on two different colors, with pan/tilt servo systems adjusting to keep the object of interest in the center of the field of view.

In this project we are using the Jetson Xavier NX, which you can pick up HERE. You will also need to of the bracket/servo kits, which you can get HERE, and then two Raspberry Pi Version two cameras, available HERE.
