摘要 针对Yanowitz和Bruckstein的二值文字图像后处理算法存在的问题,提出了一种新的基于灰度期望值的后处理算法.实验结果表明,该算法能自动选取阈值、运算速度快、处理效果好,具有良好的噪声适应性. An improved postprocessing approach based on gray level averaging is described. The proposed method can effectively solve the problems existing in Yanowitz and Bruckstein's postprocessing method. Experimental results show that both the quality of segmentation and computation speed are improved compared to Yanowitz and Bruckstein's method.
