intraframe中文什么意思
例句与用法
- a new bit rate control strategy with both global pre-allocation and local segmentation ( glas ) for low bit rate application is proposed . first, it allots bit date to every frame in advance according to possessive rate of buffer, and then distribute different quantization parameters according conctete detail . by means of this method, buffer is controlled more particularly . and the quality of decoded image is improved, the traditional video image coding method, that is to say, the intraframe coding based on dct and the interframe prediction coding based on motion compensation, is not suitable for low bit rate compression and aside from this, the encoder is too complicated
它首先在总体上根据缓存器的占有率给每帧预分配比特数，然后再根据具体细节给予不同的量化参数。使缓存器得到了更细致的控制，解码图像的质量有所改善。针对传统的视频图像编码方法，即帧内基于dct的编码加帧间基于运动补偿的预测编码存在不适于低比特率压缩，编码器复杂等不足，讨论了基于3-ddct的xyz视频图像压缩编码方法，提出了3-ddct系数的三维“z”形扫描方案，大大提高了编码效率。
