摘要：

In this paper we present a new, script-independent, HMM-based technique to locate test lines on images containing one ol more paragraphs of single-column rest. The parameters of the HMMs are trained on-line on each image using an unsupervised training procedure. We present results of line finding experiments in Arabic, Chinese ann English to demonstrate the performance as well as the script-independent nature of the technique. Comparison of HMM-based line finding with manual line finding shows that the use of HMM-based technique does not lead to a significant increase in the recognition error rate.
