Abstract: This paper describes the eliminating blue techniques in the engineering drawing recognition technology.We analyse and evaluate the existent automatic thresholding algoritm and present the nonlinear selffitted thresholding algorithm, the segmentation algorithm based on differential function, and havc made the experiment in the autonmation recognition of the architecture structure drawings.The best algorithm is not presented because we must use the special or the combined methods to process the thresholding problem for the different type degenerated drawings.
