- An advantage of wavelet-based video compression is that it offers more graceful image degradation at high compression ratios, and it also eliminates the block artifacts seen in dct compression
由小波变换编码实现的视频压缩在具备高压缩比的基础上，仍拥有较高的主观视觉效果，避免了由分块dct变换引起的方块效应。 - 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，通过选择非晶格结构的字典(原子函数之间允许重叠)，从根本上避免了低速率dct系统带来的方块边缘失真，增加估计的精度，减少对运动信息编码耗费并提高在低速率下的视觉效果。 - Experimental results show that blocking artifacts has been effectively mitigated at low bit-rates in comparing with dct based method and the proposed coding scheme is better than 3d-spiht for the scene of video sequences that move rapidly
仿真实验结果表明,与基于dct的方法相比,能够有效降低低比特率下重建视频的块失真,对运动场景变化较大的视频序列,压缩性能优于基于小波变换的3d-spiht方法。 - The analysis on the method shows that an advantage of wavelet-based video compression coding is that it offers more graceful image degradation at high compression ratios, and it also eliminates the block artifacts seen in dc compression . and it can solve the contradiction between limited bandwidth and infinitude requirements of increasing customers in present communication system
该系统充分利用人眼的视觉特性来减少帧内和帧间的冗余信息，能够消除传统图像编码的方块效应、蚊子效应等现象实现高压缩比，高质量的图像编码，可较好地解决现行通信系统中有限带宽与日趋增加的无限用户需求之间的矛盾。 - There exit two methods to compress stereo video, block-based method and block-based method . block-based method has the merits of simplicity, robustness and being easy to be implemented in hardware, but blocking artifacts may exist and the visual effect of reconstruction image may be bad in low bit rates
立体视频编码可以采用传统的块基编码方法和基于对象的编码方法，块基编码的优点是算法简单、稳健性高，易于硬件实现，但会出现块效应，在低比特率下重建图像的主观视觉效果很差。 - Wavelet transformation is a new dip ( digital image processing ) technique . as its energy is more concentrated after the transformation, which contributes to the high compressed rate with good subjective and objective assessment . wavelet transformation deals with the whole image, so it can completely remove the block artifact
小波变换是一种新兴的图象处理技术，它在变换域能量集中，所以在人的主观、客观评价良好的条件下可以获得高压缩比；而且这种变换是对整幅图象进行处理的，因此能够从根本上消除图象的方块效应。 - With the theory of wavelet transform and reversible integer-to-integer wavelet transforms based on shifting frame used in image / video compression field introduced, a new real-time implement of speck algorithm using dsp chip is provided . then the technology of motion estimation and motion compensation is discussed and an adaptive technique for the wavelet video codec to reduce the " block artifact " is presented . and the implement of the wavelet video compression system using adv611 chip is discussed next with the performance emulation result
在系统讨论了小波理论在图像视频压缩编码领域的应用后，结合dsp技术提出一种基于dsp应用的实时低存储需求的改进speck图像编码器；随后探讨基于小波变换的实时视频编码器的实现，在论述运动估计与补偿技术的基础上，针对应用空域运动估计补偿技术的低比特率小波视频编码器提出一种自适应消除块效应的技术；并讨论了基于adv611芯片的视频压缩系统的压缩性能；最后提出一种基于dsp平台具有极低时延的小波视频混合编码方案，对该方案的压缩性能进行了讨论并给出初步的硬件实现方案。 - Although some existed international video coding standards, such as h . 261, h . 263, mpeg-1 and mpeg-2, has wined great success in all kinds of commercial applications . but for all these standards, the phenomena of sensible blocking artifacts or image dithering will emerge under narrow bands, which impair the visual quality of reconstructed images . so, these standards still could n't satiate the demands of very low bit-rate applications ( under 20kb / s )
虽然已经制定的一些国际视频编码标准，如h.261、h.263、mpeg-1和mpeg-2，在各种商业应用中获得很大成功，但是在窄带条件下往往会产生人眼敏感的方块效应和图像抖动现象，损害了恢复视频的视觉质量，因此尚不能够满足在极低速率(低于20kb/s)下的应用。
