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...

Multistatic passive radar imaging using the smoothed pseudo Wigner-Ville distribution
We investigate passive radar imaging of aircraft using reflected TV signals. We apply a Smoothed Pseudo WignerVille Distribution (SPWVD)-based SAR imaging algorithm to two differe...

Benchmarking flexible adaptive time-frequency transforms for underdetermined audio source separation
We have implemented several fast and flexible adaptive lapped orthogonal transform (LOT) schemes for underdetermined audio source separation. This is generally addressed by time-...

A detection algorithm for zero-quantized DCT coefficients in JPEG
The discrete cosine transform (DCT) is widely used in image/video coding standards. However, since most DCT coefficients will be quantized to zeros, a large number of redundant co...
