Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of NAUN Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

Abstract: In view of the different recognition methods of Dai in different language, we proposed a novel method of text line recognition for New Tai Lue and Lanna Dai based on statistical characteristics of texture analysis and Deep Gaussian process, which can classify different Dai text lines. First, the Dai text line database is constructed, and the images are preprocessed by de-noise and size standardization. Gabor multi-scale decomposition is carried out on two Dai text line images, and then the statistical features of image entropy and average row variance feature is extracted. The multi-layers Deep Gaussian process classifier is constructed. Experiments show that the accuracy of text line classification of New Tai Lue and Lanna Dai based on Deep Gaussian process is 99.89%, the values of precision, recall and f1-score are 1, 0.9978 and 0.9989, respectively. The combination of Gabor texture analysis average row variance statistical features and Deep Gaussian process model can effectively classify the text line of New Tai Lue and Lanna Dai. Comparative experiments show that the classification accuracy of the model is superior to traditional methods, such as Gaussian Naive Bayes, Random Forest, Decision Tree, and Gaussian Process.
