摘要

为了有效地显示抖动图像,提出了一种新的渐进式编码方案。抖动图像是用抖动屏幕对原始灰度图像进行阈值处理的结果。该算法经过位交织预处理后,利用重排序图像的特性确定传输顺序,然后逐步重建抖动图像。此外,对抖动后的图像进行有损和无损压缩。实验结果表明,在保持低传输比特率的情况下,重建出了高质量的图像。

A new progressive coding algorithm of dithered images
A novel progressive coding scheme is presented for the efficient display of dithered images. Dithered images are the results of thresholding original gray-level images with dithering screens. After the preprocessing of bit-interleaving, this algorithm utilizes the characteristic of the reordered image to determine the transmitting order and then progressively reconstructs the dithered image. Moreover, the dithered images are further compressed by lossy and lossless procedures. The experimental results demonstrate high-quality reconstructions while maintaining low transmitted bit rates.
