Skeleton-based human action recognition with depth sensors have a renewed interest based on the development of popular depth sensors. This paper presents a new skeletal representation, Limb-based Skeleton Representation (LSR) that explicitly models 10 limbs as spherical coordinate in 3D space, and extract angular velocity feature based on the spherical coordinate representation. Using the Spherical...
Proposed in this paper is a wireless sensor network source localization algorithm in the three-dimensional space. By using the measurements of the received signal strength (RSS), two closed-form none-ambiguous estimators are proposed to geometrically locate the source position under the shadowing noise in the wireless channel. The dynamic adjustment scheme has been applied in the localization algorithm...
This paper presents a new three-dimensional positioning algorithm, named 3DPHDV-Hop, which can significantly improve the performance in terms of positioning error and coverage by using self-tune selection of projection plane and exploiting partial average hop size instead of global average hop size in wireless sensor network. The simulation results show that the accuracy of our proposed algorithm...
