零树小波编码 meaning in Chinese
ezw
Examples
- It can perform both lossy and lossless compression , and progressive codec , by providing high compression rate and image reconstruction quality
在研究嵌入式零树小波编码算法及原理的基础上,描述了算法的应用过程,阐述了具体的实现思路。 - The algorithm codes an image into multi - layer bitstream , and then the multi - layer bitstream is coded ulteriorly with the improved adaptive binary arithmetic
将图像进行零树小波编码后的小波系数符号流采用改进的自适用算术编码方法进行二次编码。 - Some novel enhancing morphologic translation algorithms such as mark , areaselect , bylsland , island are implemented in the experiment of this thesis . and what ' s more , making full use of overlapping movement compensation , embedded zerotree wavelet translation encoding and contend - based wavelet translation , this thesis has achieved the human - face - central video compression of the key objects
实验中提出了一系列新型增强形态变换算法，如mark 、 areaselect 、 byisland 、 island等，并且将交叠运动补偿、零树小波编码、基于内容的小波变换等有机地结合起来，实现了基于人脸关键对象的视频压缩。 - In this thesis , we subsequently introduce the basic concepts of wavelet transform , especially the pyramidal algorithm and its fast realization - lifting scheme ; this scheme can decrease the time and space complexity of wavelet transform greatly . wavelet transform , the most perfect mathematical tool of signal processing theory , makes great success in the field of data compression . ezw and spiht are the milestones of wavelet image coding on the noiseless channels , and jpeg2000 adopts the ebcot algorithm
嵌入式零树小波编码( embeddedzerotreewavelets )和多级树集合分裂算法( setpartitioninginhierarchicaltrees )都是迄今为止最为优秀的理想信道情形下的小波编码方案：而jpeg2000静态图像压缩国际标准采用的是嵌入式码流优化截断块式编码算法( embeddedblockcodingwithoptimizedtruncationoftheembeddedbit - streams ) 。
