*I just want to keep track of the object I selected.

frame = readFrame(obj.reader);

imshow(frame);

title('Takip etmek istediğiniz nesneyi seçin ve Enter\a basın');

rect = getrect; % Kullanıcının seçtiği dikdörtgenin koordinatlarını alır.

close; % Seçimden sonra pencereyi kapatır.

% Seçilen nesnenin sınır kutusunu global değişken olarak kaydedin.

selectedBbox = rect;

*I used the following code for this, but I do not get correct results in object tracking. I used Kalman Filter for this.

I did what you said and I follow all the objects and I get partially correct tracking, but as I said, the purpose of my project is to follow only the object I choose. What more can I do for this? I tried many methods but could not achieve results. Thank you.

Once you have selected the initial object, then in subsequent frames, you can mask out the frame beyond a reasonable maximum movement velocity, before rescanning for objects. You can also deliberately discard the tracking information about objects that are more than maximum movement velocity away from the object of interest.
