All recorded data are successfully tested for potential time skew problem and corrected based on ASR-related features. The core of the algorithm is based on perceptual time-quefrency analysis with a precision of 10 ms. The results show correct time skew detection and elimination in 100\% of cases for a real life dataset of 32 broken sessions and surpass the performance of fast cross correlation while keeping lower system requirements.}, pdf = {https://publications.idiap.ch/attachments/reports/2010/Korchagin_Idiap-RR-42-2010.pdf} } crossreferenced publications: @INPROCEEDINGS{Korchagin_ICSAP_2011, author = {Korchagin, Danil}, keywords = {pattern matching, time synchronisation, time-quefrency analysis}, projects = {Idiap, TA2}, month = {2}, title = {Automatic Time Skew Detection and Correction}, booktitle = {Proceedings International Conference on Signal Acquisition and Processing}, year = {2011}, location = {Singapore}, address = {Martigny, Switzerland}, crossref = {Korchagin_Idiap-RR-42-2010}, abstract = {In this paper, we propose a new approach for the automatic time skew detection and correction for multisource audiovisual data, recorded by different cameras/recorders during the same event.
