Worked on using DTW to map the time series of one signal to the time series of another signal.
Wrote DTW code that returns a path with this mapping, but we are unsure how to use this path to actually compare 2 signals, and determine whether they match. Hence, we decided to meet with Stern to figure out what conclusion we can get from DTW, and how this actually solves some of the issues that we experienced with our initial MFCC implementation.
We also started testing under different environments, and realised that ambient noise might be a problem. Hence we are thinking of using adaptive filters to filter noise out.
