| 摘 要： | 分析了三个算法,即嵌入式零树小波编码(EZW)、等级树编码(SPIHT)、内嵌块编码(EBCOT),提出了并行自适应码流图像编码算法.在通道内部,采用了块间剪裁算法,对于通道内小波系数的编码,加入了游程编码的思想.模拟实验证明,该算法并行性较高,在码流长度较小的情况下,效果显著.

| Abstract: | The principles of improved algorithms such as EZW,SPIHT,EBCOT are discussed.Image coding algorithm with Parallel Adaptive of Bits(P-AoB) is proposed.In each channel,an image is partitioned into many blocks,which aim to balance the distortion of the channels.After wavelet transform,the quantized coefficients are encoded using an improved bit-plane algorithm.The experiment shows that the effect is distinct if the bit rate is small or little higher. |
