An edge optimization method based on segmented surfaces of stone flakes

In our previous research, [3] has put forward a method to extract surfaces of stone flakes. But for reassembling stone flakes, it is necessary to obtain the suitable flake surface. Extracting accurate and smooth edges of stone flake surfaces plays a significant part. The former method extracted the boundary edges of stone flakes based on the density of points. However, some surface boundaries are rough. It is hard to match flake surfaces with these irregular edges. To solve this problem, an effective method is proposed for optimizing edges based on a mesh. According to experiments, results of our optimization method indicate that the boundary edges become smooth, which will make a contribute to stone flake matching.
