Non-reference p frames for temporal scalability 8受限的幀內(nèi)預(yù)測
There are spatial and temporal scalability simultaneously in three-dimensional wavelet transformation for sequence pictures, it is one of best video encoding methods in network video 視頻序列圖像的三維小波變換壓縮,同時具有空間和時間的內(nèi)在伸縮性,是網(wǎng)絡(luò)視頻傳輸?shù)睦硐刖幋a方法之一。
In addition, this coder has the function of spatial and temporal scalability . 3 . extending the previous algorithms experience to color video we create a new algorithm of joint mdc and ecn techniques 3、將md-3d-spiht與差錯隱藏的聯(lián)合抗誤碼算法擴展到彩色視頻,提出彩色視頻mdc與差錯隱藏結(jié)合的差錯復(fù)原算法。
This thesis makes a fairly in-depth study on the basic techniques about the current svc algorithms by reading a lot of relevant references, including the svc system schemes and the techniques of various scalabilities . based on these knowledge, motion compensated temporal filtering ( mctf ) which is an effective method to eliminate temporal redundancy is researched, and mctf based on db2 wavelet is presented by studying the method of mctf using haar wavelet . the simulation proves that the low-pass frame is better than the haar one, it means that the temporal scalability is improved 在此基礎(chǔ)上,本文研究了在時間可伸縮性中采用的一種有效方法:運動補償時域濾波(mctf)技術(shù),并借鑒haar小波進行運動補償時域的方法,研究并實現(xiàn)了基于db2小波的運動補償時域濾波方法,仿真結(jié)果表明該方法比基于haar小波的方法得到了更高質(zhì)量的低通幀,這也意味著在時間可伸縮性的處理上有了進一步的改善。
