Using Dynamic Programming Techniques, E.g., Dynamic Time Warping (dtw), Etc. (epo) Patents (Class 704/E15.016)
  • Audio signal decoder, audio signal encoder, encoded multi-channel audio signal representation, methods and computer program
    Patent number: 9025777
    Abstract: An audio signal decoder for providing a decoded multi-channel audio signal representation on the basis of an encoded multi-channel audio signal representation has a time warp decoder configured to selectively use individual audio channel specific time warp contours or a joint multi-channel time warp contour for a reconstruction of a plurality of audio channels represented by the encoded multi-channel audio signal representation.

  • Fast Partial Pattern Matching System and Method
    Publication number: 20110224984
    Abstract: Method, system and computer program for determining the matching between a first and a second sampled signals using an improved Dynamic Time Warping algorithm, called Unbounded DTW. It uses a dynamic programming algorithm to find exact start-end alignment points, unknown a priori, being the initial subsampling of the similarity matrix made via definition of optimal synchronization points, allowing a very fast process.
