Queuing with distortion-control for multimedia content

IEEE International Conference on Acoustics Speech and Signal Processing, 2002
There are numerous contexts in which systems need to buffer multimedia signal content. If such a buffer overflows, signal data are lost in an uncontrolled manner, which can lead to large end-to-end distortions. However, if the queued signals are distortion-tolerant, overflows can be avoided, and significant performance gains realized, by reducing the ...

DISTORTION CONTROL OF CHAOTIC SYSTEMS: THE CHUA'S CIRCUIT

Journal of Circuits, Systems and Computers, 1993
The paper presents a new approach to the control of chaotic systems for the stabilization of a periodic orbit. The problem formulation requires preserving a number of original system characteristics and making use of a low energy control. The proposed method follows a frequency harmonic balance technique employed in the approximate analysis of complex

Development of a Distortion Control ‘Toolbox’ to Mitigate Distortion in Surface Ships

Day 2 Thu, October 23, 2014, 2014
This paper describes the development of a distortion control ‘Toolbox’ that can be used to mitigate distortion in thin-structured ship design and fabrication. Highlights of the NSRP project entitled, “Distortion Control ‘Toolbox’ for Lightweight Ship Structures” are presented.

A distortion control scheme for allocating constant distortion in FD-CD video transcoder

2004 IEEE International Conference on Multimedia and Expo (ICME) (IEEE Cat. No.04TH8763), 2005
Recently, FD (frame dropping)-CD (coefficient dropping) transcoding has been considered, mainly due to the low computational complexity and simple implementation. However, CD errors in the FD-CD transcoding scheme tend to be propagated and they have a significant effect on the qualities of decoded images. We derive the error characteristics incurred by

Adaptive image coding with perceptual distortion control

IEEE Transactions on Image Processing, 2002
This paper presents a discrete cosine transform (DCT)-based locally adaptive perceptual image coder, which discriminates between image components based on their perceptual relevance for achieving increased performance in terms of quality and bit rate. The new coder uses a locally adaptive perceptual quantization scheme based on a tractable perceptual ...

MINMAX rate control with a perceived distortion metric

SPIE Proceedings, 2004
This paper presents a Rate-Distortion based optimization procedure for video coding that explicitly incorporates a perceptual distortion measure. A flexible MINMAX (minimizing the maximum distortion) optimization procedure based on Linear Programming (LP) is used to minimize the variation in distortion across frames.

Image compression methods with distortion controlled capabilities

[1991] Proceedings. Data Compression Conference, 2002
This paper presents a class of lossy data compression algorithms capable of encoding images so that the loss of information complies with certain distortion requirements. The developed algorithms are based on tree-structured vector quantizers (TSVQ).

Distortion Control and Mitigation

2016
Out-of-plane distortion results from buckling and angular deformations of panel edges as well as in the panel in between the stiffeners. The most effective way of reducing distortion is to control the formation of plastic stains produced in regions near the weld. If the appropriate distortion control is applied, the final distortion will be reduced. On

Hierarchical watermarking technique of distortion control mechanism

Proceedings of the 2nd international conference on Ubiquitous information management and communication, 2008
This paper proposed an effective information hiding scheme. The proposed scheme calculates the confidential information from a medium and embeds the information into the medium to generate the stego medium for medium integrity protection. When necessary, the verifier can extract the embedded information from the stego medium to authenticate whether the

DISTORTION CONTROL DURING MACHINING

SAE Technical Paper Series, 1964
<div class="htmlview paragraph">This report describes a nonconventional tooling procedure for machining thin-wall titanium pressure tank components. Machining had to be performed with a minimum restraint to avoid any stress buildup which could have an adverse effect on subsequent welding operations. In addition, precise contour and wall thickness
