Whereas shape analysis has largely been addressed over the last decades, the multiscale analysis of the geometry of opened planar curves has received little attention. We here show that classical multiscale techniques cannot properly address this issue and propose an original wavelet-based scheme. To highlight the generic nature of our multiscale wavelet technique, we report applications to two different observation data sets, namely, wild animal movement paths recorded by electronic tags and satellite observations of sea-surface geophysical fields. specialized Animal movements geophysical fields multiscale geometry planar curve trajectory analysis wavelet analysis 126 020 066 52 6 3627-3636 2014 0196-2892 https://www.documentation.ird.fr/hor/fdi:010087315 10.1109/tgrs.2013.2274157 0196-2892 [F B010087315] https://www.documentation.ird.fr/hor/fdi:010087315 https://www.documentation.ird.fr/intranet/publi/2023-02/010087315.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2014-04-29 2024-03-26 fdi:010087315 fre
