Feature extraction of temporal texture based on spatiotemporal motion trajectory
K Otsuka, T Horikoshi, S Suzuki… - … Conference on Pattern …, 1998 - ieeexplore.ieee.org
A framework and method are proposed to extract local features of a certain kind of naturally
occurring, non-rigid motion pattern, referred to as temporal texture. To catch both the spatial
and temporal features of this complex pattern, we focus on the surfaces of motion trajectories
in spatiotemporal space derived from multiple frames of an image sequence, and represent
the surfaces as a set of tangent planes of the surfaces. From the distribution of the tangent
planes in local regions in time and space, spatial and temporal texture features are …
