Is there any software that give us stick figures? How could I write the code by myself (in Matlab)? I know how to write Matlab codes, but I don't how to start a program that receives data points and gives back the stick figure.
Reza, I don' get your question. If u are looking for stick figure animation, there are some software on the web, like 'Pivot Stickfigure Animator', 'This Is Stick Figure Animation Theatre' and 'Stykz'. May I ask what u wanna do with these figures?
Thank you dear Steve for the answer. Actually I have some data of a marker based motion capture of human gait. So the data is tracking the human limbs movement in walking. I want to get this data to computer and then it gives me the animation or any video that reproduce the movement back.
Reza, try the bwmorp operation using 'skel' on your binary image of the object. You can then sample points from your skeleton to get data points.
Reza,
It does depend a bit on how exactly you want your 'stick figure' to look. If you have anatomical reference data for your subject, you can easily compute joint centre locations in 3D at each frame, plot lines in 3D between the joints, and update the display data using Matlab code. If you do this iteratively, you can create an animation and play it in real-time or save the frames into a movie format, also using Matlab. If you wish to work with ellipsoids or figure models, this becomes a bit more work, but the basic steps are the same.
If you'd like to see the Matlab operations involved in creating animations, you might want to download and study these files from the file exchange:
