Classify a trajectory using SVM from freeman chain codes

Hi,

Lets assume, I have set of testing trajectories (set of 2D Points) data. Now,I have generated freeman chain codes for each of these trajectory.

Now,I have a testing trajectory data,I would like to classify it using KNN and SVM. I would be glad,if someone can explain me the logic to use KNN and SVM. I really cannot understand, what can I infer from freeman chain code. All I have is codes like "02244442255333556211124".

I just want to understand the concept to apply KNN as well as SVM in this context. I am familiar with both KNN as well as SVM, but really not sure,how I can apply it here.

Thanks in advance.
