| Abstract In this paper, the DWT introduced through the design of the biorthogonal 5/3 filter bank using the lattice structure. The lattice coefficients of the proposed structure are very suitable for implementation using shift- only operations (with a single shift and add operation) instead of multipliers to perform multiplications. This results in a recognizable hardware saving when implementing such lattice structurehardwarly. The designed filter bank implemented using Matlab programming for verification. Matlab programsare also used to find the PSNR values that are taken for a group of standard gray scale images as objective criteria for efficiency, resulting in high PSNR values of around 55dB. The efficiency of the results also measured subjectively, for some standard gray scale images by comparing the original input images with the resulting onesfromcombining both analysis and synthesis sides of the proposed DWTstructure.Theefficient FPGA implementation of such design is consideredto show its simplicity.
