Paper Abstract:	In this paper, we present an approach to recover sharp edges on a triangulated mesh. A region-growing partitioning technique is used to segment the unstructured noisy mesh that allows extracting and sharpening features on a surface triangular mesh. Features are created from boundaries between mesh segments and recovered through geometry prediction by applying a nonlinear root mean square procedure to find a 3D curve. This method can be useful in computer-aided design, reverse engineering, and other applications for feature detection on the surface and for sharp edges restoration.
