| Summary: | Uncompressed multimedia data (graphics, audio and video) requires considerable storage and transmission bandwidth. A fundamental goal of data compression is to reduce the bit rate for transmission or storage while maintaining acceptable quality. Image coding and compression technique, converts an image that requires low memory storages space, smaller bandwidth for transmission, high PSNR with acceptable image quality. This paper presents wavelet based coding algorithm SPIHT to encode and compress an image data. The coding and decoding process is comparatively fast. The numerical results obtained using MATLAB shows that the output image has high value of PSNR with good compression ratio for low bit rate. |
