With the exception of the harmonic oscillator, quantum wave packets usually spread as time
evolves. This is due to the non-linear character of the classical equations of motion which …

With the hyperspectral sensor technology evolving and becoming more cost-effective,
hyperspectral imaging offers new opportunities for robust face recognition. Hyperspectral …

Sulfated zirconia with S content of 2 wt.% equivalent to complete coverage of its surface was
studied by infrared spectroscopy. At least four sulfated species were identified and exhibited …

Real-time streaming of audiovisual content over the Internet is emerging as an important
technology area in multimedia communications. Due to the wide variation of available …

In conventional motion-compensated three-dimensional subband/wavelet coding, where the
motion compensation is unidirectional, incorrect classification of connected and …

Digital images have become mainstream of late notably within HDTV, cell phones, personal
cameras, and many medical applications. The processing of digital images and video …

Scalability at the bitstream level is an important feature for encoded video that is to be
transmitted and stored with a variety of target rates or to be replayed on devices with …

A scalable video coder cannot be equally efficient over a wide range of bit rates unless both
the video data and the motion information are scalable. We propose a wavelet-based, highly …

A method and apparatus for scalable coding of a motion vector generated during motion
estimation, in which a gen erated motion vector field is separated into a base layer and an …

Scalable video coding (SVC) differs form traditional single point approaches mainly because
it allows to encode in a unique bit stream several working points corresponding to different …
