Learning dynamic time warping algorythm. In Ukrainian it is called Алгоритм динамічної трансформації шкали часу.

Watched 5 times How DTW (Dynamic Time Warping) algorithm works, than three times Dynamic Time Warping. The last is much better and explains how to handle signals of different lengths.

Read Dynamic Time Warping with Time Series.

Googling for Dynamic Time Warping accidentally have found Speech recognition for dummies (russian). Post of noob for noobs. But I find it interesting. It has:

  • explanation of .wav file format;
  • how detect periods of silence in sound calculating signal entropy;
  • what Mel-frequency cepstral coefficients are and how to calculate them.

Read interesting post Video with cloud based object detection of Raspberry Pi (russian).
