游程编码 meaning in Chinese
rlc run length coding
run-length encoding
Examples
- 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
研究了信源编解码的各种方法(包括dct 、游程编码和哈夫曼编码等)以及实现的步骤,建立了信源编码实现的结构图和程序流程图,并在vc的开发平台下,编制了信源编解码实现过程的应用程序。
