1. Increment of compression ratio is obtained while the compression quality remains not degraded. 提出了一种改进的XYZ视频编码算法,对变换后的数据采用一种更合理的扫描顺序,可以使量化后非零系数相对集中,在不损失压缩质量的前提下提高了视频文件的压缩率。
城市环境质量综合评价对城市环境受各种因素影响程度进行考察、监测和全面分析,在此基础上提出改善环境状况的政策与措施 城市是一个复杂而庞大的系统,城市环境的内涵也体现出这一特征,它包含城市的原生环境与人工次生环境。原生环境即自然环境,主要由空气、水、土壤、植物、动物和太阳辐射等构成。人工次生环境亦称文化社会...

压缩分为有损和无损压缩两种，有损压缩会影响质量，无算压缩可完全恢复，不影响质量。有损压缩广泛应用于动画、声音和图像文件中，典型的代表就是影碟文件格式mpeg、音乐文件格式mp3和图像文件格式jpg。但是更多情况下压缩数据必须准确无误，人们便设计出了无损压缩格式，比如常见的zip、rar等。所谓无损压缩...
