Recently, Uz et al. (ibid., vol.1., no.1, p.86-99, 1991) analyzed the propagation of quantization noise in a pyramid (with feedback) and subband decomposition schemes. In this study each band was independently quantized by a scalar quantizer of equal

Interpolative multiresolution coding of advance television with compatible subchannels

Autor: Martin Vetterli, Kamil Metin Uz, Didier J. LeGall

Publikováno v: IEEE Transactions on Circuits and Systems for Video Technology. 1:86-99

A multiresolution representation for video signals is introduced. A three-dimensional spatiotemporal pyramid algorithms for high-quality compression of advanced television sequences is presented. The scheme utilizes a finite memory structure and is r

Hardware design of a motion video decoder for 1–1.5 Mbps rate applications

Autor: Didier J. LeGall, Kun-Min Yang

Publikováno v: Signal Processing: Image Communication. 2:117-126

In this paper, we designed and evaluated the hardware complexity of a motion video decoder, the Bellcore proposed ISO-MPEG decoder for 1–1.5 Mbps rate applications. It is designed to perform the following features: (1) Forward normal/fast playback;

Interpolative Multiresolution Coding of Advanced TV with Subchannels

Autor: Didier J. LeGall, Martin Vetterli, K. Metin Uz

Publikováno v: The International Series in Engineering and Computer Science ISBN: 0792381823

The evolution of the current television standards toward increased quality and realism builds on higher spatial resolution, wider aspect ratio, better chroma resolution, digital audio (CD–quality) and possibly a new scanning format. In addition to
