i am doing tracking moving surface for powder with time to get an idea of the poder surface velocity with time. does anyone have any idea from where i have to start inorder to get the velocity from different time steps. i got that surace from boundary detection of the powder surface with time using images taken by high speed camera. the issue is that the surface is so random , and numer of point the decribe the powder surface is changing with time

yes i got it, but i was trying to get velocity vector field of that moving surface with time. may be by subtracting successive surface in x, and y position to be velocity in x and y direction for different points on the moving surface

the issue that the coordinate are not the same at each time step also sometimes there is more than on point in x or y direction. so it is hard to subtract two succesive curves from each other
