Paper Abstract

Image information service systems have been actively developed. It takes, however, very long transmission time for a multi-level image over narrow band channel, because the image information has a large amount of data. A variety of progressive or scalable transmission schemes have been proposed to reduce this disadvantage, which enable the receivers to recognize the image contents at the earlier transmission stage. Among these scalable transmission schemes, there are some schemes in which use bit plane coding techniques. These schemes have good performances because the resolution or the number of multi-levels can be improved independently. However, the effects of the half- tone representation at the earlier transmission stages are not good because of using the natural binary planes. In this paper, we propose a new scalable and lossless transmission method of multi-level images using the minimized average error method, which gives good quality of the half-tone reproduction. The simulation results show that our method gives good image quality at the first stage of the transmission.
