IEEE International conference on image processing
作者: K. Jostschulte A. Amer AG Schooltungen der Informationsverarbeitung University of Dortmund Germany INRS-Télécommunications Montreal Canada
The quality of a television system is significantly determined by the amount of distortions within the displayed image. One of these distortions is white Gaussian noise. So a spatio-temporal algorithm for reducing noi... 详细信息

International conference on Massively Parallel processing
作者: M. Nakamura K. Kitayama Y. Igasaki K. Kaneda Communications Research Laboratory Ministry of Posts and Telecommunications Koganei Tokyo Japan Hamamatsu Photonics K. K. Japan Fujikura Limited Japan
We experimentally demonstrate 100-m-long image fiber transmission of four-channel multiplexed two-dimensional signals. To upgrade the system throughput, we study several hundred Gb/s-class 2-D optical parallel data li... 详细信息

IEEE International conference on image processing
作者: L. Balmelli S. Ayer M. Vetterli Laboratory for Audio-visual Communications Swiss Federal Institute of Technology Lausanne Switzerland
Digital terrains are generally large files and need to be simplified to be rendered efficiently. We propose to build an adaptive embedded triangulation based on a binary tree structure to generate multiple levels of d... 详细信息

IEEE International conference on image processing
作者: Jialin Zhong Multimedia Communications Research Laboratory Bell Laboratories Lucent Technology Murray Hill NJ USA
We describe a new approach to animating generic 3D wireframe models of human heads using MPEG-4 synthetic/natural hybrid coding (MPEG4/SNHC) facial definition parameters (FDP) points and facial animation parameters (F... 详细信息

IEEE International conference on image processing
作者: S.D. Servetto C.I. Podilchuk Beckman Institute Department of Computer Science University of Illinois Urbana-Champaign Urbana IL USA Multimedia Communications Research Department Bell Laboratories Lucent Technologies Inc. Murray Hill NJ USA
We consider the problem of coding video signals using motion compensation and a forward coded dense motion field. First, we develop a motion estimation technique that yields dense estimates suitable for the coding app... 详细信息

1997 conference on visual communications and image processing
作者: Hammerle, J Uhl, A Univ. of Salzburg (Austria)
Fractal image compression is computationally expensive. Therefore speedup techniques are required to achieve time demands comparable to other compression techniques. In this paper we combine sequential and parallel te... 详细信息

1997 conference on visual communications and image processing
作者: Wang, DM Wang, LM Communications Research Ctr. (Canada)
Global motion estimation and compensation are important research issues in video compression. The main difficulty in global motion estimation resides in the disturbance of independently moving objects. The algorithm p... 详细信息
