TY - JOUR ID - 1349484 AU - Sedmidubský, Jan - Eliáš, Petr - Zezula, Pavel PY - 2016 TI - Similarity Searching in Long Sequences of Motion Capture Data PB - Springer International Publishing AG CY - Cham (ZG) SN - 9783319467580 KW - motion capture data KW - similarity search KW - subsequence search KW - multi-level segmentation N2 - Motion capture data digitally represent human movements by sequences of body configurations in time. Searching in such spatio-temporal data is difficult as query-relevant motions can vary in lengths and occur arbitrarily in the very long data sequence. There is also a strong requirement on effective similarity comparison as the specific motion can be performed by various actors in different ways, speeds or starting positions. To deal with these problems, we propose a new subsequence matching algorithm which uses a synergy of elastic similarity measure and multi-level segmentation. The idea is to generate a minimum number of overlapping data segments so that there is at least one segment matching an arbitrary subsequence. A non-partitioned query is then efficiently evaluated by searching for the most similar segments in a single level only, while guaranteeing a precise answer with respect to the similarity measure. The retrieval process is efficient and scalable which is confirmed by experiments executed on a real-life dataset. ER -
