  1. By choosing non - hybrid dictionary, blocking artifacts of dct system can be avoided ultimately. the cost of coding motion information is reduced, so the visual quality of images at low bit - rates is improved. 4

    而且,通過選擇非晶格結構的字典(原子函數之間允許重疊) ,從根本上避免了低dct系統帶來的方塊邊緣,增加估計的精度,減少對運動信息耗費並提高在低下的視覺效果。
  2. This paper analyses the rate and distortion of multiple description based on this method. we formulate the rate and distortion models based on the analysis

    摘要對分層多描述進行了理論分析,並通過對以及與量化步長關系的分析,建立了分層多描述模型。
  3. We improve the real - time and quality performance of a scalable 3d wavelet coding scheme, mc - ezbc, and then focus on the joint rate - distortion target model of the mc - ezbc transcoding and propose a rate - distortion optimized layered rate control method

    本文對可伸縮三維小波演算法mc - ezbc實時性能和質量進行了改進,在此基礎上,重點研究了mc - ezbc轉換的聯合目標函數和優化演算法,提出了優化的mc - ezbc轉換分層控制方法。
  4. So if we gain the relation between the the derivative of ggd distortion - rate function and the ggd shape parameter, then we can reconstruct the rate - distortion function. the bitplane - based fgs of mpeg - 4 has been accepted as a standard coding tool for video streaming applications

    這樣,實際中只需研究特定量化模式下ggd函數的導數與ggd形狀參數的關系和規律,就可以重建相應模式下的函數。
  5. In this thesis, firstly, we introduce generalized gaussian distributions to model the distributions of dct coefficients of an el frame. then, according to quantization theory, we analyze the distortion - rate function of the generalized gaussian model, with which we conclude that for the actual fgs coding, the derivative of actual distortion - rate function usually decreases continuously as the rate increases, and then begins to increase slowly at a comparatively high bit rate. finally, guided by the

    然後分析了fgs的量化模式,並把它應用到ggd分佈上,得到了ggd分佈函數的變化規律,從而獲得實際fgs函數的變化規律,即fgs函數的導數先隨著的增加而逐漸減小,然後在比較高的時候開始隨的增加而緩慢地增加。
