本文针对低带宽的应用要求对原算法进行改进，增加了对系统性能影响比较大的i帧的码率控制模型，并考虑场景变化的影响，对量化值的调整方法进行了改进。 | | 2. | Whereas , one problem in all mainstream coding schemes is that the statistical redundancy among pixels is considered as the only adversary of compression , while the perceptual redundancy is totally neglected , though it is well known that any criterion is not as eloquent as the visual quality of an image . it is to say , the rate distortion performance is mainly used as the evaluation criterion for the previous video compression standard . although rate distortion is adopted abroadly , it does not completely reflect human vision speciality
然而众所周知,任何判断标准都没有视觉质量更具有雄辩力,但所有的编码机制都仅仅考虑象素间的统计上的冗余,而完全忽略了知觉上的冗余,也就是说以往视频压缩编码技术的评价准则以率失真性能( rate - distortionperformance )为主,虽然这一指标被广泛采用,但并没有完全反映人类的视觉特性。 | | 3. | Based on analyzing the results of the software implementation and the complexity of different wavelet transform , the integer - integer lifting wavelet transform is adopted . and a fast algorithm suitable for hardware implementation for t2 encoder in jpeg2000 is presented in this paper , based on the elaborate analysis of rate distortion optimization scheme and code stream organization , and its architecture project of hardware design is shown in detail

数据重传必然会引起延迟，因而在需要很短延迟的应用中是行不通的，如双向无线通信同时在以广播方式进行数据传输时也是行不通的当有大量突发错误时，纠错码如分组纠错码block code及卷积码convolutional code无法在不产生额外延迟及需要额外运算的前提下对数据提供足够的保护而错误掩蔽的性能则受接收到数据与丢失数据之间的残留相关性大小的影响。 |
