Transmission of Images Using SPECK


Pragya Tiwari, Mohd Ahmed, S.G.Kerhalkar


Vol. 14  No. 11  pp. 97-101


Compression is the process of representing information in a compact form so as to reduce the bit rate for transmission or storage while maintaining acceptable fidelity or data quality. The objective of this paper is to develop an efficient compression scheme and to obtain better quality and higher compression ratio using Multiwavelet transform with Set Partitioned Embedded block coder algorithm (SPECK). In our tests, we employ Scenes derived from standard AVIRIS hyper spectral images, which possess 224 spectral bands. The performance of the SPECK is compared with SPIHT& JPEG2000.The quality of compression and reconstruction is measured by quantitative measures like PSNR
