Entire shape reconstruction of dynamic objects is an important research subject with applications on film production, virtual reality, modeling and engineering. Typically, entire shape reconstruction of real objects is achieved by combining the outcome of objects scanned from multiple directions. However, due to limitations on the number of 3D sensors enclosing the scene, occlusions inevitably occur, causing holes to appear on the reconstructed surfaces. These issues are intensified if dynamic, moving objects are considered. Volumetric and polygonal approaches exist to address these problems. Most notably, exemplar-based polygonal methods have gained momentum due to their overall improved visual quality. In this paper we propose an extension to the plain exemplar-based technique that allows for multiple dynamic objects. With our method, adequate hole-filling candidates are sampled from spatial and temporal domains and then used to synthesize likely plausible surfaces with smooth boundaries for the hole regions.
