H.264/AVC scalable video extension (SVC) adopts various advanced prediction modes to exploit the data redundancies between layers for better coding efficiency but at the cost of significantly increased computational complexity, especially for hardware realization of fractional motion estimation. This paper proposes an efficient and hardware friendly mode pre-selection algorithm which only preserves...
In this paper, the field decomposition method is used to split the homogeneous Bi-isotropic media into two uncoupled isotropic media instead of direct calculation of complicated Green's function in Bi-isotropic material. The construction of formulation using Poggio-Miller-Change-Harrington-Wu-Tsai (PMCHWT) integral equation for multiple homogenous dielectric objects and the electric field integral...
The SET k-cover problem is an NP-complete combinatorial optimization problem, which is derived from constructing energy efficient wireless sensor networks (WSNs). The goal of the problem is to find a way to divide sensors into disjoint cover sets, with every cover set being able to fully cover an area and the number of cover sets maximized. Instead of using deterministic algorithms or simple genetic...
In this paper, a priority-based normalized partial distortion search algorithm for fast motion estimation is proposed. The proposed algorithm is mainly composed of the two algorithms, the priority-based normalized partial distortion and the dynamic search range decision algorithm. Firstly, the distortion behavior of each macroblock is analyzed in this paper to point out the calculation priority/order...
In this paper, a fast block-based motion estimation algorithm which combines the finite-state side match concept for H.264 video coding standard is proposed. The proposed algorithm performs the side matching for each candidate position within the search window and chooses several positions which have least side match sum of absolute difference to form a finite-state motion vector set. Afterwards,...
