html5 technology has great technical advantages and influence on the graphical image processing function of mobile devices. The purpose of this study is to evaluate the performance of html5 graphics and image processing and co-rendering technologies and to verify the effectiveness and usefulness of these technologies, including the measurement of user experience and efficiency. The simulation analysis is carried out on MATLAB, and different image compression algorithms are used for comparison. The evaluation indexes include peak signal-to-noise ratio (PSNR) and structural similarity (SSIM). Comparing the two methods of Joint Image Expert Group (JPEG) and fractal Image Compressed file (IFS), the results showed that the proposed algorithm provided better PSNR and SSIM values than IFS, and provided higher PSNR and lower SSIM values than JPEG under the condition of increasing compression ratio, showing excellent image processing and compression efficiency. Then, the correlation loss, brightness distortion, contrast distortion, and color distortion of image processing are analyzed for the four real scenes of blur, illumination, cloud, and strong light. The results showed that compared with JPEG and IFS, the correlation loss of the proposed algorithm was 15.46, 16.25, 16.78, and 17.45, respectively. It had lower correlation loss, brightness distortion, contrast distortion, and color distortion, and showed better image processing effects. In general, the study found that the graphics and image processing and co-rendering technology based on html5 has high efficiency and effect in image processing and compression, especially in complex environments and conditions, such as fuzzy conditions, lighting conditions, cloudy weather, and strong light conditions, showing excellent performance and adaptability. This discovery provides important evidence for its practical application in many fields such as computer vision, medical imaging, and remote sensing image analysis, and helps

In view of the low efficiency of data visualization and the slow speed of database reading and writing when the current data visualization system is dealing with the front-end development data of mobile social Web, a data visualization system for front-end development of mobile social Web based on html5 is designed. The data collector is used to collect and store the front-end development data of mobile social Web, and the visual controller is used to communicate with the visual external devices to complete the hardware design of the system. Preprocess the Web front-end development data to ensure the data dimension differences within a reasonable range, divide the data into html5, JavaScript, CSS three different forms of files, classify low dimensional data and high-dimensional data, design two types of data visualization interface, complete the system software design. The experimental results show that the reading and writing speed of the database of the design system is accelerated, the data insertion time, query time and visualization time are effectively shortened, and the efficiency of information visualization is improved.

LogicCircuits is a tool for direct or flipped-classroom teaching, and even self-study of digital circuits in computer engineering. It is html5-based and thus runs on all current platforms and operating systems in a browser. Its features include simple logic gates, combinatorial and sequential logic circuits, 4-valued logic, a VHDL-export of modeled circuits, and automatic generation of exam tasks that can be solved at home.

Importance of this work comes from the fact that more and more attacks on information resources are made using html5 vulnerabilities every year. This work contains a theoretical study on the methods and possibilities of attacks using html5. Basic schemes of XSS and CSRF attacks, attacks on CORS, and intelligence-gathering activities in isolated network segments have been developed. As a practical example, an algorithm for implementing a CSRF attack has been considered and scenarios for preventing this attack have been developed. The outcome of research in this domain is a number of protective methods which have been developed against the basic types of attacks.

Field geological practice is not only an important part of teaching. However, how to vividly explain the geological practice in the field and intuitively show the geographical environment and its evolution is a difficult problem for geological educators. In this study, we use Pingtan Island as a research case. Based on html5 and open-source framework *** of network graphics library WebGL, 3D interactions were embedded in the website. Besides, POI was built through Java, and annotation and image information were marked so as to realise data uploading, navigation, and 3D simulation platform functions. The research is to form a theoretical and practical teaching system.
