摘要
提出了一种二维斜分指数交叉熵的印章图像阈值分割方法,借鉴二维直方图的斜分思想对二维指数交叉熵直方图进行斜分。实验结果表明,相对于最大熵法和指数熵法,提出的二维斜分指数交叉熵的印章图像阈值分割方法分割效果更佳。
The exponential cross entropy thresholding method based on 2-dimensional histogram oblique segmentation is pro-posed by using 2-dimensional histogram vertical idea . A large number of experimental results show that in contrast with the maxi-mum entropy method and the exponential entropy method , the exponential cross entropy thresholding for seal image based on 2-di-mensional histogram oblique segmentation can achieve superior segmented results and greatly reduce the running time .
