This paper discuss the compression of an image using lifting scheme to implement SPIHT (set partitioning of hierarchical trees). The SPIHT algorithm uses dynamic data structure that does not make it possible for use in a hardware system. Here the implementation of SPIHT algorithm using lifting scheme in system c is done, so that it becomes suitable for implementation in FPGA. The hardware implementation is done in a XILINX XC3S500E device.

Here the implementation of SPIHT algorithm using lifting scheme in system c is done, so that it becomes suitable for implementation in FPGA. The hardware implementation is done in a XILINX XC3S500E device.
