@article{Viswanath2010WaveletTD, title={Wavelet to DCT transcoding in transform domain}, author={K. Viswanath and J. Mukherjee and P. Biswas and R. Pal}, journal={Signal, Image and Video Processing}, year={2010}, volume={4}, pages={129-144} }

Wavelet to DCT transcoding provides inter-operability between standards using the two transforms for encoding. Transcoding in transform domain avoids inverse transform and re-transform operations and saves computation. In this paper, we propose new algorithms for transcoding wavelet coefficients to block DCT coefficients. In the first step, the wavelet coefficients are transformed into upsampled DCT coefficients. Subsequently, these trans-formed coefficients are synthesized in the block DCT… Expand
