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.
