Gesture Recognition with Line Integrals

Not sure what is intended, but it seems to have some bugs?<p><a href="https:&#x2F;&#x2F;assets.opentoken.com&#x2F;sha256&#x2F;N1ShZ7kcVmH_-auZEGaGOS_baJxgQTG2" rel="nofollow">https:&#x2F;&#x2F;assets.opentoken.com&#x2F;sha256&#x2F;N1ShZ7kcVmH_-auZEGaGOS_b...</a><p>Ah nevermind, it&#x27;s matching the curve against template fields so it makes sense that it would show the best match even when the match is poor.

I created a method similar to this one for curve extrapolation based on sample curves. I took the second derivative of each point on the training data, added it&#x27;s contributions to a vector field.<p>To extrapolate, you can take &#x27;position&#x27; and &#x27;velocity&#x27; of live data and integrate over the vector field to produce an extrapolation. I enjoyed the project and it worked fairly well. I think there&#x27;s plenty of room for extension around this method.

It was ridiculously hard to get 4 to work, is this a limitation of the algorithm or just something with the implementation?

Cool but how is the math used to recognize gestures?
