| Abstract: | The lossless compression algorithm for color images based on the RCT-DWT-SPIHT is researched.The results show that this method can be better accomplished lossless image compression coding.International standards of 24 color images of the simulation test results show that this algorithm is more than JP2,RAR,ZIP,PNG,TGA,PCX,TIF lossless compression algorithm is on average increased by 7%,30%,41%,44%,62%,63%,66%.This transformation can be additive and shift complete,easy hardware implementation. |
