How to allow the user to specify pixels in browsed video?

I want to make GUI that allows the user to browse video, then it can determine some points in the video. For example: The browsed video will be a road with cars and the user will determine a car from the video. I know how to allow browsing video, but how can I allow her to determine some points?

New in R2018b is the Video Labeler App. If you have 18b and the Computer Vision System Toolbox you can can load a video and label objects like cars. https://www.mathworks.com/help/vision/ref/videolabeler-app.html

Thank you so much! I would ask if the app can retrieve to me the positions of the objects that I label it?
