| Abstract: | An image lossless compression coding performance is researched for Deslauriers-Dubuc(m,n)interpolating wavelet transform with SPIHT based on lifting scheme .experimented result indicate that The Transform is integer-integer invertible transform based on lifting scheme and integer operation , suitable fast and in progressively until to image lossless compression .performance of lossless compression is well good then popular Huffman?WinRar? Raw WinZip?JPEGLS. For example in (4,4) by comparison whit these method average improved the compression rate by about 63%,49%,46%,34% respectively . due to invertible transform is based on integer operation may be by addition and shift completed, so that fast and easy to dynamic image coding and hardware implement. |
