Hi,
I am working with a thing flexible structure, I have got images from experiments. I want to know how I can trace an edge and get its mpvement for example in terms of displacement and velocity verses time?
Image is attached.
Thanks

Do you have a method to locate the edge already? That would be the first step. Maybe try hough() or houghlines() if you don't have a method yet.
After that you can get the endpoints and centroid locations. Then make an array where you keep track of those 3 locations from frame to frame. Multiply by a spatial calibration factor to get distances in real world units such as millimeters. Velocity is the change in distance divided by the frame time.
