In the text, A method of image watermarking based on DCT (Discrete Cosine Transform) domain algorithm is proposed and verified in experiment by Matlab. The experimental result shows that the current method can achieve embedding with sound robustness and invisibility. From the experimental results, the quality of the watermarked image is almost no decline relative to the original.
Combined with the actual situation, this paper explores how to develop a crawler method based on the specific framework for the complete interface of steam manufacturers and stores, which should be able to automatically and efficiently crawl the data of specific targets, analyze the dynamic pages, and complete the data cleaning, downloading, saving and other operations, explore the methods of general data analysis, and Analyze the downloaded data, extract useful information from it, analyze and summarize the specific crawler method and data analysis method through practical application.
This topic takes Vue framework as the front-end framework of e-commerce middle office management system, uses springboot framework as the construction mode of back-end framework, and uses Java to write function code. [1] The data of the system is stored in MySQL database, which can be provided to the employee end of registered employees and the management end of managers. Employees can complete registration and login through the e-commerce middle office management system, and then view department information, store information Warehouse information and view order information and add, view commodity file information. The system administrator manages employee information, department information, store type information, store information, warehouse information, commodity file information and order information through the management end. Through the realization of the different functions of the above employees and administrators, the normal operation of the system is ensured, and the process involving stores, commodities and orders is monitored, So as to make a complete set of e-commerce middle office management system that can be provided to all kinds of users.
With the rapid development of domestic Internet, more and more people choose housing leasing activities through the Internet, however, the existing housing rental information website the quantity many, but because of various advertising, information is scattered, so to HOME LINK sites, according to the position provided by the customer, accurate demand such as rent or house type, vertical search related data from the rental information website and in accordance with the provisions, the structure of the storage, rent information data to provide data for subsequent analysis. Bring users a faster experience. At the same time, we should add the reminding of the houses we are interested in and the reminding of price reduction. For the users who cannot look at their mobile phones all the time, timely reminding can help them avoid missing many desirable houses. This system is committed to solving the current people to rent a request for the search of detailed provide the keywords needed. To help make it easier for everyone who needs to rent. The system is mainly composed of data cleaning, data access, algorithm design and implementation, Python implementation of the front and back end of the system, data formatting and auxiliary decision.
