摘要：The recent availability of inexpensive hardware,such as CMOS and CCD cameras,has enabled the new research field of wireless multimedia sensor networks. This is a network of interconnected devices,capable of retrieving multimedia content from the environment. In this type of network,the nodes usually have very limited resources,in terms of processing power,bandwidth and energy. Efficient coding of the multimedia content is therefore important. A new image compression codec,suitable for this type of network was developed,a very high compression ratio can be achieved,the compression rate varies depending on the content but it is usually between 90% and 99% compared to the previous camera network.
