The Tibetan language, as the language of the tubo period, recorded the life, history and other important events of the Tibetan people, and is a treasure of Tibetan culture. Aiming at the problem of the loss of Tibetan documents caused by the yellowing, blackening and rotting of papers due to the old age, a new method for the segmentation of Tibetan documents is proposed. In order to better protect Tibetan documents and reveal the contents recorded in the documents. The method uses the improved NLM (non-local means) algorithm to de-dry the pre-processing, and uses the automatic region-blocking GMM (Gaussian Mixture Model)+K-means multi-feature fusion algorithm to segment, using multi-region classification extraction as post-processing of the Tibetan documents. Experimental results show that compared with k-means, GMM and other algorithms, this method can more effectively segment the text in Tibetan literature, proving the effectiveness and accuracy of this method.
