Research of Image Thresholding Segmentation Algorithm for Laser Carving

In the light of the major problems existing in the current laser engraving image processing software such as lack of third-dimension and lifelikeness, missing detail information, having pattern trace, this thesis using visual characteristics of the human eye, the pattern dithering method in print areas apply to the process of gray image field of laser engraving. In addition, improvement on the traditional dithering method, pattern matrix becomes homogeneous matrix by calculating, solves the problem of trace pattern, and improves the quality of carving.
