摘　　要：提出了一种二维直分指数交叉熵的印章图像阈值分割快速算法。利用二维直方图对二维指数交叉熵进行阈值选取,导出快速算法。实验结果表明,提出的二维直分指数交叉熵的印章图像阈值分割快速算法相对于最大熵法和指数熵法,不仅分割结果精确,运行时间也相应缩短。In this paper, exponential cross entropy thresholding for seal image based on 2-dimensional histogram vertical is proposed. Exponential cross entropy threshold selection based on 2-dimensional histogram vertical was derived , its fast algorithm is given. A large number of experimental results show that exponential cross entropy thresholding for seal image based on 2-dimensional histogram vertical can achieve superior segmented results and greatly reduce the running time , in contrast with the maximum entropy method and the exponential entropy method.
