Multi-video Object Synopsis Integrating Optimal View Switching

In this paper, we propose to integrate multi-video object synopsis with the display method of optimal multi-view switching. We group occurrences of the same object in different cameras together and operate them in the same way, based on which we propose a unified framework that optimizes object-based synopsis variables and multi-view switching variables simultaneously. The unified formulation encodes activity, occlusion, chronological order, and view switching costs. We develop an alternative optimization scheme composed of graph cuts and dynamic programming to minimize the combined costs efficiently. This integrated framework provides a more user convenient browsing approach for object-based synopsis results, and allows to further reduce occlusion artifacts between synopsized objects. Experiments demonstrate the effectiveness and user convenience of our multi-video synopsis method.
