Seamless image-based texture atlases using multi-band blending

In this paper, we propose a novel method for creating a high-quality texture atlas from a 3D model and a set of calibrated images. Our method focuses on avoiding visual artifacts such as color discontinuities, ghosting or blurring, which typically arise from photometric and geometric inaccuracies. We first compute a partition of mesh faces which realizes a good trade-off between visual detail and color continuity at patch boundaries: we efficiently obtain a close-to-optimal seam placement using graph cuts optimization. We then apply a pixel-wise color correction in the vicinity of patch boundaries with a principled 3D extension of multi-band image blending: we achieve faultless color continuity while avoiding ghosting artifacts. We demonstrate the effectiveness of our method on two real-world large-scale scenes.
