Tracking single object using computer vision system toolbox

I have a video which is mainly consist of a wire( in black) and the background is sky

I want to detect the movement on upper side and lower side of the wire( vibrations )and store them and finally plot them. I had a look on one of MATLAB examples multiple object tracking and I want to adopt the same approach on my own video.

When I am trying to change the video input I am receiving these error(s) I am new to MATLAB and I do not have any clue how to resolve it

can anyone help ?

Thanks a lot

Hi, can you please tell us which version of MATLAB, and what kind of operating system you are using?

In the mean time, try replacing line 85

   obj.videoPlayer = vision.VideoPlayer('Position', [20, 400, 700, 400]);

with

   obj.videoPlayer = vision.DeployableVideoPlayer();
