Gif has a medium compression ratio and can retain more information than jpeg . gif files are generally of larger size ; and Gif的影像压缩比率属比率较高一般,而且可保留的资料精确度较jpeg为高多。
According to the analysis of reconstruct image , using the algorithm can get an excellent image compression result 根据对压缩图象的结果进行分析,本压缩方案在压缩比低于30时达到了较好的压缩效果。
Film 35 mm ; image produced by camera aperture and projected image area , anamorphotic method , lateral compression ratio 2 : 1 and aspect ratio 2 , 35 : 1 35mm胶片.采用变形法按横向压缩比为2 : 1和宽高比为2 . 3
Jpeg has a relatively higher image compression ratio but the compression is lossy original image cannot be perfectly reproduced Jpeg的影像压缩比率较高,但压缩后会失真(不能完美无暇地复制原本影像) 。
Jpeg has a relatively higher image compression ratio but the compression is lossy ( original image cannot be perfectly reproduced ) Jpeg的影像压缩比率较高,但压缩后会失真(不能完美无暇地复制原本影像) 。
Ali current video coding standards such as h . 263 + employ variable length codes ( vlc ) , to achieve high compression efficiency 在现在流行的视频编码标准中(例如h 263 + )均使用可变长编码( vlc )来获得高效的压缩比。
Gif has a relatively higher image medium compression ratio and can retain more information than jpeg . gif files are generally of larger size ; and Gif的影像压缩比率属比率较高一般,而且可保留的资料精确度较jpeg为高多。
Experimental results show that , compared to the jpeg 2000 , our method have significant improvement in the visual quality under the same compression ratio 实验表明该算法在相同的压缩比下能明显提高复原图像的视觉效果。
The experimental results show that a better reconstructed image can be got by few iterations at roughly the same compression ratio ( cr ) 实验结果表明该方法在保持一定的压缩比的情况下,只须少数迭代就可得到理想的恢复图像。
Experimental results show that the model achieves higher lossless compression rate of image than lossless spiht and lossless ebcot used in jpeg2000 实验结果表明,利用这种模型获得的平均无损压缩比高于spiht和用于jpeg2000的ebcot 。
