Hi there, I want to measure the growth rate of some crystal structures that I grow. I have a video of the growth, but I don't know how to set up a code or command to analyze the growth rate from that video. Does anyone have any ideas?

There is a similar MATLAB Answers post that could possibly help you achieve your workflow.
You can find that in the following MATLAB Answers page:

Similar to that post, you could perform edge detection in MATLAB (if you do not use Simulink) in every frame in order to find the growth rate.
You can find more information on edge-detection in the following documentation link:
