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
它首先在總體上根據緩存器的佔有率給每幀預分配比特數,然後再根據具體細節給予不同的量化參數。使緩存器得到了更細致的控制,解碼圖像的質量有所改善。針對傳統的視頻圖像編碼方法,即幀內基於dct的編碼加幀間基於運動補償的預測編碼存在不適于低比特率壓縮,編碼器復雜等不足,討論了基於3 - ddct的xyz視頻圖像壓縮編碼方法,提出了3 - ddct系數的三維「 z 」形掃描方案,大大提高了編碼效率。The research results are controlled source which has linear or nonlinear variabe frequency scan function and the seismic instruments which match with it, and the method of small group intervals, small offset, much more channels, short array length, high - frequency receivers are applied during the link of data acquisition, and that the techniques of the refraction static correction, the noise suppressing, the high - resolution velocity analysis, the wavelet length compression, the wavelet zero - phase, and the prestack migration should be applied emphasizedly during the link of data processing and interpretation
