In 1996, the JPEG committee began to investigate possibilities for a new still image
compression standard to serve current and future applications. This initiative, which was …

One of the purposes of this article is to give a general audience sufficient background into
the details and techniques of wavelet coding to better understand the JPEG 2000 standard …

Is it possible to leverage WiFi signals collected in bedrooms to monitor a person's sleep? In
this paper, we show that with off-the-shelf WiFi devices, fine-grained sleep information like a …

Non-invasive human sensing based on radio signals has attracted numerous research
interests in recent years. Previous work mainly focused on detecting the presence of a …

This paper presents an efficient metric for quantifying the visual fidelity of natural images
based on near-threshold and suprathreshold properties of human vision. The proposed …

Interest in image compression for internet and other multimedia applications has spurred
research into compression techniques that will increase storage capabilities and …

The discrete wavelet transform (DWT) decomposes an image into bands that vary in spatial
frequency and orientation. It is widely used for image compression, measures of the visibility …

Variable rate is a requirement for flexible and adaptable image and video compression.
However, deep image compression methods (DIC) are optimized for a single fixed rate …

Wavelets and wavelet packets have recently emerged as powerful tools for signal
compression. Wavelet and wavelet packet-based compression algorithms based on …

The authors have been beguiled and entranced by mathematics all of their lives, and both
believe it is the highest expression of pure thought and an essential component-one might …
