Interactive Mesh Segmentation Based on Feature Preserving Harmonic Field

Mesh segmentation plays an important role in many applications in computer graphics. This paper presents a novel mesh segmentation algorithm based on the harmonic field defined on the mesh. Initially, the user marks a few freehand sketches on the mesh to specify the region of interest. The algorithm then automatically constructs the harmonic field to reflect the details of features of this region. The graph cut technique is then applied to produce the segmentation result which is consistent to the user's intention, and the boundary is further smoothed to remove the artifacts. Experimental results show that our method can generate satisfactory results for models with either simple or complicated shape details.
