An Efficient VLSI Architecture for 3D DWT Using Lifting Scheme
The role of the compression is to reduce bandwidth requirements for transmission & memory requirements for storage of all forms of data as it would not be practical to put images, audio, video alone on websites without compression. The medical community has many applications in image compression often involving various types of diagnostic imaging. The use of wavelet transform is now well established due to its multi resolution & scaling property. Among the various techniques the authors have used the lifting scheme as the lifting scheme allows perfect reconstruction by its structure. The system is fully compatible with JPEG 2000 standard. The most important property of this concept seems to be the possibility of simple and fast applications into FPGA chip.
