ROI编码技术在JPEG2000中的应用∗
Application of ROI Coding Technology in JPEG2000
摘要
Abstract
With the rapid development of internet and multimedia technologies,the quality and function of image is better and better. At the present,the standard of JPEG can not satisfy our demand,So ISO developes a new standard of JPEG2000. A coder system of JPEG2000 image compression standard is mainly designed in this thesis. The main results are outlined as following:1)lift wavelet transform. The most difference between JPEG2000&JPEG is that JPEG2000 gives in block coding major for DCT in JPEG but adopts the multiresolution-based coding major for DWT. Lift wavelet transform is adopted in this thesis. It has fast velocity,less complexity of compute and need less storage. 2)Embedded block coding. Self-adapting binary arithmetic coding is adopted in this thesis in JPEG2000. 3)Region of Interest. Introduction of how to create the ROI mask the application of ROI technology in JPEG2000 is briefed.关键词
