A design is proposed based on the new coding scheme for a novel image compression algorithm SPIHT (Set Partitioning In Hierarchical tree) using wavelet transform and arithmetic coder that provide an embedded code word. Image compression using SPIHT attracts more interest due its low memory requirement to represent an image. Due to its inherent redundancy the algorithm is suitable for both color and gray images. SPIHT display several important properties over other image compression algorithm like fast coding and decoding, high compression ratio, application in lossless image compression, good image quality, high PSNR value and it has a capability to code for exact bit rate.
