With the rapid development of microblog, the research of topic detection has been paid more attention, which has begun to transfer from the traditional news media to microblog. However, compared with the traditional fields where topic detection applied, the microblogging data is written informally and the structure of that is not rigorous, which will bring great difficulties. In the process of topic...
Digital watermark is an effective copyright protection method. A new robust public watermarking algorithm is proposed with the base of the method of confidence evaluation and neural network data fusion. First a special addition formula is applied to later evaluate the confidence of each extracted watermarked bit in the extraction. Then a normalization is used to accord with the approximate distortion...
Nowadays digital watermarking has played an important role in the copyright protection of multimedia. A new robust watermarking algorithm is proposed with the base of error correcting code (ECC) and data fusion by evidence theory and distortion factor. The algorithm does not need any mask or original image during the extraction and makes the watermark more robust and further more the data fusion composed...
