The Art Of Electronics

Let us discuss today how you can detect and track an object in real-time. We will be using Python language and Opencv library for this purpose. Check out the video below. If you have read my previous blogs, you can directly skip down to the contour part. As usual, we need to make a few assumptions for the proper working of this application. This background is always static i.e. there is no addition or subtraction of objects in the background scene. The background-color is always constant. It does not change with time. The object that will be used for writing/painting is of a different color than the background to give us sufficient contrast between foreground and background. We are ready to begin now. Let us start by installing necessary python libraries for our project using  pip install.  We will be needing  Numpy  and  Opencv  libraries. Now create a python project and create a new script. Import the required libraries into python script as shown below. import cv2

Today we will be discussing how you can write/paint in the air using your finger. We will be using Python language and Opencv library for this purpose. Check out the video below. Ok before starting we need to make a few assumptions for the proper working of this application.

Today we will be discussing how you can write/paint in the air using a colored object. We will be using Python language and Opencv library for this purpose. Check out the video below. I think you now get the idea of what we will be doing. Ok before starting we need to make a few assumptions for the proper working of this application.
