XIAOBO
- 小波分析有它独特的特点。它的压缩比高、压缩速度快 , 压缩后能保持信号与图像的特征基本不变 ,且在传递过程中可以抗干扰。可以克服传统方法产生的缺陷 ,因此获得了较好的压缩效果。 -Wavelet analysis has its unique characteristics. Its high compression ratio, compression speed, compressed to maintain the basic characteristics of the sign
coding
- 此代码是在保持信噪比的情况下，进一步提高了压缩比。灰度级的减少，势必会降低信噪比，但因为是处以比较小的整数，并没有引起熵值的剧烈变化，编码后信噪比基本不变。-This code is to maintain the signal to noise ratio of the case, to further improve the compression ratio. Gray-scale reduction, will inevitably reduce the signal to noise
