A Method of Document Segmentation Using Hidden Markov Tree Models By Two Steps

YANG Xiao_yi ,HOU Yu_hua (Department of Mathematics,Henan University,Kaifeng, 475001, Henan China)  
In this paper, we introduce a new document segmentation method based on wavelet transformation and the hidden Markov tree (HMT) model by two steps. With the method, background is firstly made certain based on the smooth image, and then the two-state HMT model is applied to text and image. At last we illustrate that the method is more effective than the two-state HMT model proposed in .
