In this paper, we propose a novel approach to seamless texture stitching on a 3D mesh. The main idea is to blend the sampled images by least-angle selection of gradients in overlapping patches. This is in contrast to previous works which focus on vertex-or face-based strategies with additional heuristics for robustness. Patches are obtained by growing a uniform mesh segmentation via geodesic projections. Blending is achieved by formulating a screened Poisson equation using discrete differential
