摘要
多媒体信息呈几何级数的爆炸性增长,带来海量信息的同时也带来庞大的数据量,加重了网络的负担,同时不同用户对所要接收图像的质量要求有所不同,如果以相同的标准进行处理势必会造成一定程度上信息的浪费。文章对静止图像的渐进编码作了进一步的研究,对基本层和增强层采用不同的编码策略,更加适应网络复杂多变的带宽条件。文章还通过与用户之间的交互式操作来满足用户不同的需求。实验结果表明,在压缩效果达到JPEG压缩标准的情况下,增强了渐进功能,更加适应网络需要。
Multimedia gave us numerous information with numerous data,it make the internet crowded.Because there are different requirements on picture quality from different consumers,we can treat them differently.In this paper,we research on still picture,give different method to base and improved stream,the different requests of the consumers will be satisfied through the interactive operation.
