Paper Abstract

Image compression is now essential for applications such as transmission and storage in data bases. Set Partitioned Embedded Block Coder (SPECK), introduced by Asad Islam and Pearlman, is a very effective and computationally simple technique for image impression. In this paper we present a new image coding method based on SPECK, which provides even better performance than previously reported it. The new method changed the test way in set to reduce the execution time, and provided fast encoding/decoding. The experiment results show that the PSNR of the new algorithm is higher, the MSE of the new algorithm is lower, and the execution time of the new algorithm is less than SPIHT and SPECK algorithm obtained at the same rate-compression. Especially, the executing time of the new method is much less than the SPECK. In addition, this scalar quantized scheme, which change the test way in set, has the potential for small memory usage.
