Research Progress on the Application of Grey Theory in Image Engineering
灰色理论在图像工程中的应用研究进展

With the increasing maturity of traditional image information processing,from the point of theories and utilities,it is of great importance for researchers to find new theories and new ideas based technology.First,this paper briefly introduces the research contents,main characteristics and basic theories of grey theory.Then the state-of-art of grey theory in image engineering is summarized and analyzed in three levels: image processing,image analysis and image understanding.In addition,some research fruits of the authors are reported.Finally,some key issues and perspectives of grey theory in image engineering are pointed out.Research conclusions show that in spite of a new theory in image engineering,grey theory is feasible,efficient and almost covers all the fields of image engineering.
