Trackbar OpenCV Python – A trackbar is a window with a channel and optional tick marks, as well as a slider (sometimes known as a thumb) in it. The trackbar provides notification messages to signal a change when the user adjusts the slider using the mouse or the direction keys.
Importance of Trackbar Python OpenCV
Trackbars in OpenCV are useful for quickly changing a variable value without having to close and relaunch the program.

Trackbar OpenCV Python : About the project
This 2022 Trackbar OpenCV Python was created with Python OpenCV. Trackbar is a graphical user interface element that allows the user to select a specific color value from a range of options by sliding a slider linearly. It’s similar to scrolling, but it restricts the user’s ability to choose a specific value by setting minimum and maximum bounds.
The cv2.createTrackbar() method in OpenCV creates a trackbar; the cv2.getTrackbarPos() function reads the current position of the trackbar slider; and the cv2.setTrackbarPos() function changes the trackbar’s position ().
This Trackbar In Python also includes a downloadable Python Project With Source Code for free, just find the downloadable source code below and click to start downloading.
