Abstract
A method for the simultaneous localization and recogni-
tion of dynamic hand gestures is proposed. At the core of
this method is a dynamic space-time warping (DSTW) al-
gorithm, that aligns a pair of query and model gestures
in both space and time. For every frame of the query
sequence, feature detectors generate multiple hand region
candidates. Dynamic programming is then used to compute
both a global matching cost, which is used to recognize the
query gesture, and a warping path, which aligns the query
and model sequences in time, and also finds the best hand
candidate region in every query frame. The proposed frame-
work includes translation invariant recognition of gestures,
a desirable property for many HCI systems. The perfor-
mance of the approach is evaluated on a dataset of hand
