Effects of compression and onset/offset asynchronies on the detection of one tone in the presence of another

The Journal of the Acoustical Society of America, 2014
The weaker of two temporally overlapping complex tones can be easier to hear when the tones are asynchronous than when they are synchronous. This study explored how the use of fast and slow five-channel amplitude compression, as might be used in hearing aids, affected the ability to use onset and offset asynchronies to detect one (signal) complex tone ...

A lossless 2-D image compression technique for synthetic discrete-tone images

Proceedings DCC '98 Data Compression Conference (Cat. No.98TB100225), 2002
A new image compression technique, flexible automatic block decomposition (FABD), losslessly compresses typical discrete-tone pseudo-color images 1.5 to 5.5 times more compactly than GIF, and up to twice as compactly as JBIG. The algorithm is designed to exploit the two-dimensional redundancy in an image by expressing the image in terms of itself ...

Lossless compression of continuous-tone images (HP)

2000
Lossless compression of images is an important research field, nowadays. In this paper, we survey some of the recent advances in lossless compression of continuous-tone images. The modeling paradigms underlying the state-of-the-art algorithms, and the principles guiding their design, are discussed in a unified manner.

The effect of elastic compression on the venous tone in patients with varicose veins.

VASA. Zeitschrift fur Gefasskrankheiten, 1992
The long term effect of elastic compression, with an emphasis on the changes in venous wall elasticity, was studied in 10 limbs with varicose veins. By simultaneously measuring venous volume, using the air plethysmograph (APG), and venous pressure, while the venous outflow was occluded, the pressure/volume (P/V) relationship of the venous system of the
