Subband Image Coding Using Cosine Modulated Filter Banks with Perfect Reconstruction and Linear Phase
lye propose a lossy image coding scheme based on the recently introduced even-stacked cosine modulated filter banks (CSIFBs) that allow linear phase filters in all channels. We des...

Lossy and lossless compression for color-quantized images
An efficient compression scheme for color-quantized images based on progressive coding of color informationhas been developed. Rather than sorting color indexes into a linear list...

Linear Joint Source-Channel Coding for Gaussian Sources through Fading Channels
Abstract— We consider the linear coding of a discrete memoryless Gaussian source transmitted through a discrete memoryless fading channel with additive white Gaussian noise (AWGN)...

Efficient Implementation of the Generalized Tunstall Code Generation Algorithm
A method is presented for constructing a Tunstall code that is linear time in the number of output items. This is an improvement on the state of the art for non-Bernoulli sources, ...
