摘要：
Implementation complexity will have a dramatic influence in facilitating the deployment of the JPEG-2000 technology in consumer market products. This paper addresses the computational complexity evaluation of the new standard's compression engine. A non-optimised C code implementation of JPEG-2000 is profiled at run time using an automatic profiling tool built in house. The computational complexity measurements generated by the profiler are presented and discussed in the paper. The comparison between JPEG-2000 and JPEG baseline computational complexity is also presented.
