Abstract: Conventional image compositing algorithms are designed for homogeneous environments. These algorithms do not take heterogeneity into account and do not make use of the properties of an order-independent compositing operator. As for order-independent image compositing problems in a heterogeneous environment, these algorithms usually can not make full use of the resources. An order-independent image compositing algorithm in heterogeneous environments was proposed, which was able to distribute the workload according to computing and networking characteristics, and managed to optimize compositing scheme by utilizing the properties of order-independent operator. A comprehensive evaluation on the ns-3 network simulator was conducted. Experiment results show when the environment has great heterogeneity, the algorithm will gain significant speedup over classical algorithm binary swap.
