Application of Optimal boolean Filter in Document Image Processing

Abstract

In this paper, the problem of designing optimal Blloan filter under the mena absolute error (MAE) criterion is sloved completely. the applications of the optimal Boolean filter have been successively extended to document image enhancement and extraction of text characters from overlapping text/background image. The performance and operation theory of optimal Boolean filter against other competitive techniques are compared. The feasibility fo training Boolean filter is also confirmed by experimental results in case that the original image is not available.
