Abstract :
In this paper, a parallel system together with a real-time workload balancing algorithm is proposed for view synthesis on multi-core platforms. First, a numerical relationship between the number of holes after warping and the workload of view synthesis is derived based on correlation analysis for the texture regions. Then, according to the location of the holes (whether they lie around an edge or at a homogeneous region), different models are proposed to predict the synthesis workload accurately. Experimental results show that the workload difference among cores is reduced largely and higher speedup ratio is achieved with negligible quality degradation by the proposed workload balancing system.
