| 摘 要： | 根据最大熵原理提出了一种用二维最大熵获取二值图象的新方法，介绍了用梯度－区域灰度均值二维最大熵求取阈值的原理和过程。计算机仿真结果表明，采用本文提出的阈值分割方法，对于直方图平坦的灰度图象处理效果尤为理想。

| Abstract: | Based on the maximum entropy principle,this paper presents a new method of obtaining binary images by the use of 2-D maximum entropy At the same time,the mechanism and procedure of threshold evaluating through 2-D maximum entropy of gradient and local gray-level mean are also described The results of coxmputer simulation have proved that the processing effect with the method presented is very fine for gray-level image whose histogram is even' |
