“…This strategy ensures extraction accuracy and reduces the impact of watermark embedding on the original central view. Experimental data show that the method has good robustness and invisibility [20]. At the same time, the teaching method is more in line with the heuristic concept, and finally, the student evaluation is used as evidence of the effect test in the teaching system.…”

When the information society has become the mainstream environment, various applications of big data and computers have been popularized in various industries. Multimedia technology has always been a special part of the computer field. In audio, video, image processing, and transmission, multimedia information processing has become the main means to solve the above problems. The performance of this information processing technology is extremely powerful. It can not only process dynamic data but also complete the transmission task in the big data environment. Visual communication design is a way of transmitting information to the masses by using various effects, and it has its advantages in the selection of images, video, text, and other processing technologies. This paper mainly studies the concept, method, and application effect of visual communication design under multimedia information processing. Firstly, the application of multimedia information processing technology in various fields and countries is investigated. Based on the literature analysis and statistics, the advantage tendency of this technology is judged. Starting from the visual functions involved in visual communication, the application effect of the multimedia 3D image processing and rendering communication platform is used. The gray function is used to build the multimedia information processing platform and form a complete and effective evaluation system. Finally, the visual communication design optimized by multimedia processing technology is further analyzed to improve the defects of dynamic images in visual applications and further improve the impact of visual communication design on the masses. The results show that multimedia information processing technology can improve the efficiency of image data processing in visual communication design, and has a good impact on visual communication of dynamic information.

“…Hence, these watermarking algorithms based on image feature points with better robustness to resist the geometric attacks were discovered, such as Harris detection [26,27], Harris-Laplace detection [28], scale-invariant feature transformation (SIFT) [29], and affine scale-invariant feature transformation (ASIFT) [30]. During the detection process, the watermark is less prone to synchronization error.…”

With the rapid spread of network information, the information maintenance has become the focus of information security on networks. Digital watermarking is one of the effective methods to protect information security, achieve anticounterfeiting traceability, and protect copyright, and it is an important branch of information hiding technology. However, one of the most challenging questions of digital watermarking is how to present strong robustness in geometric attacks. Nowadays, most watermarking algorithms are relatively weak robustness against geometric attacks. A robust watermarking algorithm against geometric attacks based on the non-subsampled shearlet transform and the Harris-Laplace detector is proposed. The host image is decomposed into subbands with different directions by the shearlet transform, and the Harris-Laplace detector is utilized to obtain the feature regions. Then, the nonoverlapping regions with strong robustness are selected to embed watermark by the fuzzy c-means cluster algorithm. The experimental results indicate that the proposed watermarking scheme can well resist geometric attacks.
