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

A wavelet to DCT progressive image transcoder
A transcoder design is proposed in which the transcoder loads the pre-encoded embedded wavelet coefficients and computes the DCT coefficients, which are quantized and sorted by multi-grid embedded coding to output a compressed DCT bitstream. Expand

A comparative study of DCT- and wavelet-based image coding
It is believed that the image and video compression algorithm should be addressed from the overall system viewpoint: quantization, entropy coding, and the complex interplay among elements of the coding system are more important than spending all the efforts on optimizing the transform. Expand

DCT convolution and its application in compressed domain
A discrete cosine transform (DCT)-domain convolution theorem is developed which besides exploiting the sparseness of the DCT-domain representation also exploits the orthogonality and symmetry in the D CT- domain representation to lead to efficient compressed domain-based processing methods unlike their spatial domain counterparts, where such properties are not available.

Image resizing in the compressed domain using subband DCT
Though there is a marginal increase in the computation required in image-halving, the computation overhead of the proposed modification is higher compared to the Dugad-Ahuja algorithm in the case of doubling the images. Expand
