| 摘 要： | 在MPEG-2标准的基础上研究,从硬件设计和算法性能的角度出发,开发了两种方案的无损视频压缩系统算法。对比于最好的无损静态图像算法JPEG-LS和CALIC算法,实验结果显示我们设计的算法在压缩率上,超过JPEG-LS算法最高为70%,超过CALIC算法最高为65·9%。

| Abstract: | In this paper,based on the schemes designed in MPEG-2,we develop two different algorithm designations for lossless video compression system from the points of view of hardware design and performance.When using JPEG-LS and CALIC,the existing state-of-the-art in lossless compression of still images,to formulate the benchmarks,our experiments illustrate that the proposed algorithms outperform JPEG-LS by up to 70% and CALIC by up to 65.9%. |
