| 摘 要： | 基于离散小波变换DWT(Discrete Wavelet Transform)的JPEG 2000代表着静态图像的最高水平.HEVC(High Efficiency Video Coding)提出了一个静态图像压缩档次——Main Still Profile,其帧内编码模式采用多种新的算法实现.通过大量实验比较发现,基于HEVC静态图像压缩比JPEG 2000具有更高的压缩效率,将来有望取代JPEG 2000成为新的静态图像压缩标准.

| Abstract: | Since JPEG2000 that based on Discrete Wavelet Transform came out in 2001, it has been standing for the highest level of still image compression. In January ,2013, the latest generation standard of video compression was published. With new structure and algorithm, its performance can be 1 time higher than H.264/AVC High Profile. In HEVC, a profile for still image compression is proposed, Main Still Profile, its intra mode has adopted many new algorithms. Results show that HEVC can achieve much better performance than JPEG2000,and is quite potential to be the next generation method for still image compression. |
