The formula shows that the deflect degree first increases , then decreases , and its maximum increases while the compress rate decreases 分析表明,斜交桥下的水流流向偏转角度随斜交角度的增大先增大后减小,其极大值随压缩比的减小而增大。
The experiments show that this algorithm surpasses those traditional coding method in compressing rate and it is competitive in speed and time with those traditional coding method 实验表明,这种算法在压缩率上优于传统的算法,在编码和解码速度上接近于传统的数据编码方法。
H . 263 + is one of the mature standards to deal with high compress rate and strong channel error correction ability , which could be perfectly used in wireless video communication areas 面向甚低码率的h . 263 +标准则是能较好地解决高压缩效率和强信道冗错能力的成熟标准之一,能较好地应用于无线视频通信领域。
Experimental results show when image compressing rate is high , decoded image of wavelet transform based compressing method can preserve objects outline well and has no block effect which may appear in dct block coding technique 从运行结果可以看出,当图像压缩率较高时,使用基于小波分析图像压缩方案的解码图像能保持清晰的轮廓,无dct块编码压的方块效应。
We decompose an image through the wavelet transform functions made by us , the original image can be better restored , and the experiment of single image shows the compressing rate is 50 : 1 . the compressing efficiency is further improved 用所构造的小波变换把图像分解后,能比较好地恢复出原始图像,从单帧图像的实验说明压缩比可达50 : 1 ,进一步提高了压缩效率。
