- The subimage of the lowest frequency ( ll4 ) is carried out lossless compressed coding ; 2 the subimages on diagonal direction of the highest frequency ( hhl ) is abandoned and is not carried out coding , because it is of great probability for zero , and it little affects visual
其主要包括对最低频子带单独进行无损压缩编码，对最高频对角线方向子带舍去不编码。对其余各子带根据视觉特点的不同，分别分配不同的比特数并按其进行零树量化，最后再游程编码。 - Secondly , on the basis of the research on the characteristics of the wavelet coefficients , the combination of the ezw ( embedded zerotree wavelet ) and advanced rle ( run length encode ) is presented to realize the efficient codes of the wavelet coefficients . finally , the improved periodic extension algorithm is used to solve the boundary problem appeared in wavelet transform . the algorithm is realized by software and the good processing results are obtained
论文选取cdf ( 2 , 2 )小波基，取得了较好图像压缩效果；二、通过对小波系数的特点的研究，提出了将嵌入式零树编码和改进的游程编码相结合的方法，实现了小波系数的有效编码；三、采用改进的周期延拓法解决图像进行小波分解时出现的边界问题，并通过软件实现，取得较好的处理效果。 - 2 . reseach different methods and steps carried out including discrete cosine translation , run - length enconding and haffman encoding about signals coding and decoding . the signal - coding structure diagrams and programmable flow charts are not only established but also the applide program about signal coding and decoding is complied on vc developable flat
