摘要：This paper has made an analysis to color realistic restoration problem for Terracotta Warriors, and combining with graphic knowledge, two types of being solved key issues are extracted. Based on color transfer and aiming at the two key issues, the technology framework of color realistic restoration for faded Terracotta Warriors is put forward. Then, an improved Welsh algorithm is proposed to match color pixel, which using local eigenvalues and neighbor variance to form mixed distance measure function. The results of recolor experiments to natural scenery texture and gray texture of Terracotta Warriors show that, the improved color transfer algorithm of this paper is better in recolor gray texture than classical Welsh algorithm, especially for the painted texture which has hierarchical color structure
