该算法解决标准中原算法码率分配过于平均和不能充分利用已编码帧历史信息的问题。
参考来源 - 基于H.264的码率控制算法So a rate-distortion optimizer for the SPIHT is designed to give an adaptive lifting of the rate-distortion slopes, which not only makes up the deficiency of bit allocation in SPIHT, but also protects the spectral information efficiently.
基于上述研究结论,该算法在光程差方向上,逐渐提升率失真函数的斜率,增大对图像的保护程度,这样不仅弥补了SPIHT算法在码率分配上的不足,而且有效的保护了傅里叶域中的光谱信息。
