This paper proposes a research framework for graphic digital text Watermarking algorithms and methods. We summarized graphic text watermarking after a brief review of digital text watermarking, and propose the research framework that consists of 8 levels, such as pixel, line, etymon, character, row, paragraph, page, and chapter. According to the embedding methods, each level is divided into three...
Because of the low quality and large size of population sequence data, calling population structural variations (SVs) genotypes is still a challenging problem. In this paper, we propose an SVM-based approach for genotyping deletion and insertion polymorphisms with population sequence reads. The key idea of our approach is combining multiple sources of information contained in sequence data in calling...
Based on technology of domain ontology, Chinese ancient poetry learning system provides the high knowledge relevance among poems, poet, allusion, genre etc., and presents knowledge according to the user's preference and educational level. It explores approaches to automatically analyzing of genre, allusions and interpreting unlisted poem online.
In this paper, a simple and efficient method for coarse classification of Chinese characters is presented. In the new approach, a Chinese character is characterized with its outmost and second-peripheral segment features, each of which is expressed as four string vectors. The outmost and second-peripheral segment features of a Chinese word describe the structure of segments in top, bottom, left and...
A fast and effective fade detection algorithm is proposed in this paper, which directly operates in compressed domain and suitable for real-time implementation. By analyzing the prediction directions of B frames, which are revealed in the macroblock types, the candidate fades can be found. Then, uncommon intracoded macroblocks of the P frame can be applied as an indicator of fade. As a result, locating...
