After the preprocessing of bit-interleaving, this algorithm utilizes the characteristic of 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.application/pdf137979 bytesapplication/pdfzh-TW國立臺灣大學電機工程學系暨研究所順序累進編碼半色調影像無失真壓縮Progressive codinghalftone imagelossless compressionreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/8041/1/932213E002100.pdf
