Abstract In this research work, the VLSI based 2D-DWT (Discrete Wavelet Transformation) with lifting method is proposed to improve the performance. Discrete Wavelet based simulation generates efficient image compression with higher compression ratios. Lifting method based 2D-DWT is implemented by using the 1D-DWT architecture with improvement in the picture resolutions. In general, the two dimensional discrete wavelet transform is performed by using the two levels, the predict method is performed in the initial stage and the next stage is performed in addition. By implementing the DWT, the input samples are decomposed into the various sub bands of the signals with both time and frequency data. VLSI architecture is used to further improve the performance of the transformations. The proposed architecture has been implemented by using the VHDL Modules. The flexible efficient architecture is easily designed by using VHDL modules. The simulations are performed by using Modelsim XE to check the validations of the wavelet transformations. Image compression is achieved by using MATLAB R2013 to generate the efficient image pixels for the input image by using 2D-DWT.
