I have a video of worm-like objects which move. They can move in a straight line, they can rotate in circles, they can move in a serpentine/winding/sinuous way. I need to track them.
I already have all the necessary code to track them by finding their contours so I have all the "topological" information necessary however there is one last thing I am not able to do so far: finding their center.
What I mean by center is of course not the center of mass or of gravity or of simmetry, but rather the mid-point, the center along the line that goes from head to tail.
I need it because if the worm rotates or steers, the center-of-mass does not move much but the mid-point of the worm is actually moving.
Does abybody have any suggestion?
Here an example of the kind of images we are dealing with:
