Enhancement of Discrete Wavelet Transform (DWT) for Image Transmission over Internet
Kamrul Hasan Talukder, Koichi Harada · 2011
In this paper, a wavelet-based image transmission scheme has been proposed. The proposed scheme has used discrete wavelet transform to transform a digital image from spatial domain into frequency domain. For wavelet transformation phase, Haar wavelet transformation has been used. However, it is computationally rigorous. Use of concurrent computing has significantly reduced computation time overhead as well as the transmission time up to 80% to 82% as compared to the existing sequential discrete wavelet based transmission while maintaining the accuracy of the reconstructed image.
