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. 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 import numpy as np To captur...
In this blog, you will get to learn a lot about computer vision. The blog posts are written in such a way that even a newbie can understand. This blog tries to clear the most fundamental concepts of image processing and computer vision.
