this is working all the way up to adding in the crowd/swishes now
revamped Gesture_Recognizer to do some legit machine learning on gestures; right now, its accuracy is pretty incredible. First of all, I am representing each gesture as a sequence of 7 frames instead of 1, which the frames much more widely spaced, in order to get rid of very high transition probabilities from a state to itself. I train an HMM for each gesture; in order to classify a new gesture, I get the log_prob of the observed gesture on each hmm, and feed the outputs into a multinomial-LR curve. on the testing data alone, it performs very well. now to test on actual, real-time data.
