| There are a number of problems to be solved in image compression to make the process viable and more efficient. A lot of work has been done in the area of wavelet based lossy image compression. So the proposed methodology of this paper is to achieve high compression ratio in images using 2D-daubechies Wavelet Transform by applying global threshold for the wavelet coefficients The proposed work is aimed at developing computationally efficient and effective algorithms for lossy image compression using wavelet techniques, where This paper proposes a modified simple but efficient calculation schema for 2D-daubechies wavelet transformation in image compression. The work is particularly targeted towards wavelet image compression using daubechies Transformation with an idea to minimize the computational requirements by applying global compression threshold for the wavelet coefficients and to improve the quality of the reconstructed image. The promising results obtained concerning reconstructed images quality as well as preservation of significant image details. The numerical results have been presented by using matlab programming. | ||
