Missing some block on Optical Flow SIMULINK?

Hello,
I am attempting to pull a velocity value from a video feed. To do so I am using the Horn-Shunk method. Following an example i have built a SIMULINK system that should output a velocity values, but i seem to be missing some components. I cannot find the including “optical flow lines” and “Motion vector”. Are these blocks specific subsystems, are they something i should be able to find, or are they part of an outdated version of SIMULINK? Unfortunately the example does not make it clear.
The example's URL is posted below.

There is an Optical Flow block in the Computer Vision System Toolbox.
