Abstract. In this paper, we present a HAnd Mesh Recovery (HAMR) framework to tackle the problem of reconstruct-ing the full 3D mesh of a human hand from a single RGB image.1 In contrast to existing research on 2D or 3D hand pose estimation from RGB or/and depth image data, HAMR can provide a more expressive and useful mesh representa-.

We propose a novel two-step data-driven mesh denoising approach. The first step removes noise by learning normal variations from noisy models to their ground-truth counterparts. Unlike existing denoising methods, we present the second step to recover the mesh geometry lost in the first step. The second step understands the commonly used filters
