symmetric periodic meaning in English
周期对称
Examples
- The advanced algorithm consists of three parts . by choosing more suitable biorthogonal wavelet basis and symmetric periodic extension to improve the compression quality . since most energy focus in the low frequency part , a little distortion will effect the quality of entire image heavily
由于最低频部分集中了绝大部分能量，其失真将严重地影响整个图像的恢复质量，因此对其进行单独处理，本论文尝试了采用dpcm方法进行编码，充分利用了低频系数的相关性，提高了压缩比。
