Design of A Progressive Image Compression Algorithm and Its Implementation on Multilevel Archives Management System

According to the stipulations set forth in the Archives Law of the People’s Republic of China, the Digitalization Specification for Paper Archives (DA/T31-2017), and other pertinent legal norms, the reliability of electronicarchive sources necessitates strict adherence to standardized procedures and specific elements. Notably, the scanning of paper archives into an electronic format requires a specific scanning resolution. However, using a higher scanning resolution inevitably results in considerably larger file sizes for the scanned electronic-archive images. This challenge is exacerbated when numerous users concurrently access archives, consuming a large amount of network resources and bandwidth. The resultant network communication congestion directly affects the overall user experience during archive exploration. In response to this challenge, this paper introduces an innovative progressive compression algorithm designed for bitmap image processing within the multilevel management system of electronic archives. This cutting-edge method significantly improves the compression ratio of electronicarchive images compared with conventional approaches. As a result, it alleviates the strain on network resources, optimizing the user browsing experience for electronic archives.
