TrackBar OpenCV Python With Source Code

The TrackBar OpenCV Python was developed using Python OpenCV, Trackbar is a GUI element that let the user to select a specific color value within a range of values by sliding a slider linearly. It’s similar to scrolling but it limits the user to select a specific value with its minimum and maximum limits.

What is OpenCV?

OpenCV (Open Source Computer Vision Library) is an open-source computer vision and machine learning software library. OpenCV was built to provide a common infrastructure for computer vision applications and to accelerate the use of machine perception in commercial products.

A trackbar in OpenCV provides cv2.createTrackbar() function, to read the current position of the trackbar slider you can use cv2.getTrackbarPos() function to change the position of trackbar use cv2.setTrackbarPos().
