| Abstract: | The concept of wavelet transform and its application in image processing is introduced. The problems confronted with implementing the wavelet transform in hardware are particularly illustrated, and then the corresponding scheme for resolving these problems is provided. Finally the paper analyzes the advantage of implementing the core of wavelet transform in FPGA. |
