In this paper, a new multiscale technique for digital halftoning and embedded multiresolution rendering is proposed. The proposed algorithm is adaptive by tuning a threshold value, the dithered patterns used to producing the illusion of grayscale information at constant and small varying areas can be preserved and the high frequency information can made more visible. In addition, the halftoning images possess the property of embedded multiresolution rendering. That is, the down sampled version of the halftoning image can be directly obtained from the original halftoning image. The proposed algorithm can be used for not only displaying the halftoning images at multiple resolutions but also having the potential for progressive transmission and image compression.
