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 ().
