Hello! How can I sum, e.g, 5 consecutive video frames to visualize the trajectory of the objects in a video? Thank you!

Hello Joana,
This can be solved by first generating the frames of the video and then adding any frames in any desired order we want.
Here's the link to extract frames from a video and here's the link to the documentation for adding images.
Hope this solves the question.

If you have the frames already in a 3D array, then you might want to consider using movmean or movmedian
window = 5; dim = 3;
mmf5 = cast(movmean(YourFrames, window, dim), 'like', YourFrames);
The cast() is there because movmean() will take the mean as double precision, but the result would not be something you could display as easily if the original data is uint8 .
