AI for Everyone LESSON 29: Control of Real World Objects with Gesture Recognition in Mediapipe

In this video lesson we show you how you can control objects in the real world using OpenCV, Python, Mediapipa and our old friend, the Arduino. On the Python side, we recognize hand gestures, and then we pass the recognized gesture to Arduino and Arduino lights LED in response to what hand signal is seen. This is a simple example, but a very powerful method. Instead of LED, you could operate servos, stepper motors or relays to control any manner of different devices. For your convenience, this is the code we used on the Arduino side:

And on the python side, we used the following code.

 

Improved Gesture Recognition in Python and MediaPipe

In this video lesson we show you how you can improve the accuracy of your gesture recognition program developed in the last lesson. We do this by normalizing the hand landmarks distance matrix to a standard size. By doing this, you get accurate results independent of the distance your hand is from the camera. For your convenience, I include the code below which we develop in this lesson. Enjoy!

AI for Everyone LESSON 26: Accurate Gesture Recognition using Python and MediaPipe

In this lesson we demonstrate how to use mediaPipe and Python to create an AI system that can accurately recognize hand gestures. This is follow on work to what we developed in Lesson 25. The code we developed is presented below.

 

AI for Everyone LESSON 25: First Attempt at Using MediaPipe for Gesture Detection

In this lesson we describe what our approach will be to creating a gesture detection and recognition algorithm using mediaPipe. We will demonstrate the algorithm with some simple code demos. In future lessons we will further develop the algorithm.  The code below is the initial algorithm developed in this video. Enjoy!

 

Parsing Mediapipe Data for Pose Landmarks, Hand Landmarks and Face Bounding Box


 

In this lesson we show how to create python classes to parse the data coming from Mediapipe for hand Landmarks, Pose Landmarks and the bounding boxes for found faces. Creating these classes allows the difficult parsing to be done in the class, and then have a simple way to parse and use all the data.
