Aiming at DNA encoding sequences design, a micro-genetic algorithm (MGA) is proposed by introducing a sharing function based on similarity and H-measure of DNA sequences. In the algorithm, six design criteria are adopted and four genetic operators are applied. Compared with the previous results, the algorithm can get better DNA sequences and improve the computational efficiency.
Digital watermarking is a means to protect multimedia copyright, and it will be subjected to various attacks. Therefore, the research on the robustness of watermarking algorithm is considered as a hot field. A digital image watermarking algorithm that can resist geometric attacks is proposed based on chaos game representation and normalization. Firstly, the original image is mapped to the geometrically...
