Reliefs are widely used as decorations for various things as medals, buildings and porcelains. If we can generate a bus-relief that represents multiple objects overlaid, the range of motifs that can be expressed on reliefs will be expanded. In this work, we propose a novel bas-relief modeling algorithm from two range data each of which represents the base and foreground pattern of a relief. The algorithm solves Poisson equation to conform the gradient of the relief height function to the gradient of the foreground pattern. Empirically it was shown that the algorithm can generate bas-relief models with foreground patterns not affected by the base features.

Keywords: bas-relief, range images, gradient of pixel value, Poisson equation
