比特平面编码是一种多值灰度图象的二值编码技术。本文将这种方法推广并应用于准动图象(即冻结图象序列)帧间差值信号的压缩编码,获得了满意的效果。文中论述了帧间比特平面编码的原理,讨论了编码参数的选择,并给出了实验结果。实践证明,本文编码方法为实现数字静态图象传输提供了又一条有效途径。 Bit-plane coding is a binary coding technique for multi-valued gray-scale images. In this paper, this method is generalized and applied to the compression coding of the interframe difference signal in the quasi-dynamic image (ie frozen image sequence), and the satisfactory result is obtained. This paper discusses the principle of interframe bit plane coding, discusses the choice of coding parameters and gives the experimental results. Practice has proved that this coding method provides another effective way to achieve digital still image transmission.
