Brightness Control With Hand Detection OpenCV Python With Source Code
This 2022 Brightness Control With Hand Detection OpenCV Python With Source Code was developed using Python OpenCV, This Python OpenCV Project With Source Code we are going Building a Brightness Controller with OpenCV , To change the brightness of a computer.
Building a Brightness Controller with OpenCV can be accomplished in just 3 simple steps:
- Step 1. Detect Hand landmarks
- Step 2. Calculate the distance between thumb tip and index finger tip.
- Step 3. Map the distance of thumb tip and index finger tip with volume range. For my case, distance between thumb tip and index finger tip was within the range of 15 – 220 and the volume range was from 0 – 100.
What is OpenCV?
OpenCV is short for Open Source Computer Vision. Intuitively by the name, it is an open-source Computer Vision and Machine Learning library. This library is capable of processing real-time image and video while also boasting analytical capabilities. It supports the Deep Learning frameworks.

Gesture recognition helps computers to understand human body language. This helps to build a more potent link between humans and machines, rather than just the basic text user interfaces or graphical user interfaces (GUIs).
In this project for gesture recognition, the human body’s motions are read by computer camera. The computer then makes use of this data as input to handle applications.
