Temporal error concealment for video transmission

2004 IEEE International Conference on Multimedia and Expo (ICME) (IEEE Cat. No.04TH8763), 2005
In this paper, we propose a temporal error concealment algorithm for video transmission in an error-prone environment. The error concealment algorithm employed an edge detection algorithm and progressive median motion vector concealment. First, the edges are detected and concealed portion by portion.

Data transmission and error correcting codes

ICASSP '82. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
Data transmission simulation, protected by error correcting code, through noisy channel, is one of A.A.E.C.C. principal research axis. We present two parts of an application of our works ; befor that, we present some recalls of error correcting codes 'theory. a) The hardware part. Automaton DOLVRON-1, completely elaborated in A.A.E.C.C.

Error control and concealment for image transmission

IEEE Communications Surveys & Tutorials, 2000
In the practical transmission of compressed still images, bit errors may occur, which probably result in desynchronization and packet loss. In packet-switched networks, network congestion also results in packet loss. This survey article reviews the error resilience factors that must be faced by a robust image encoder and decoder (codec).

Error detection and correction of transmission errors in SPIHT coded images

Proceedings. International Conference on Image Processing, 2003
This paper presents a novel scheme to improve the robustness of set partitioning in hierarchical tree (SPIHT) based color image coder for transmission over noisy channels. In this scheme, the SPIHT bit streams are re-arranged according to their spatial (square block) representation without loss of coding efficiency.

Creativity: relation to neural transmission errors

Kybernetes, 2011
PurposeThe purpose of this paper is to compare creativity and psychometric IQ and to explain why creativity is often related to mental disturbances.Design/methodology/approachThe approach taken is that of theoretical analysis.FindingsPsychometric IQ is found to be related to low probability of neural transmission errors.

Games with random errors of information transmission

Automation and Remote Control, 2015
Consideration was given to the hierarchical two-person games with a fixed order of moves. It was assumed that there were some random errors of information transmission. Examined was a model where both players were guided by the corresponding expectations for their gains.

Transmission Error Calculation Based on Manufacturing Errors and Load

Advanced Materials Research, 2014
A valid mathematic model is introduced to study the calculation of gear meshing transmission error, which is based on the manufacturing error and gear teeth deformation. Subsequently, take a pair of specific gear for example;The transmission error curves are obtained by the calculation model.

Encoder error analysis in gear transmission error measurement

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 1998
This paper investigates encoder measurement error and introduces a method of reducing or cancelling the encoder error from gear transmission error signals. The time domain and frequency domain analysis of the combined encoder error signals has been carried out to show the validity of the method.

A Note on PCM Transmission Error

IEEE Transactions on Aerospace and Electronic Systems, 1970
PCM system transmission error causes error in the subsequent reconstruction of a quantized analog signal. A concise proof is given for bounds on this error (either mean square or mean absolute value). This proof requires no assumptions regarding source distribution or number of quantization levels.

A Novel Unequal Error Protection Approach for Error Resilient Video Transmission

2005 IEEE International Symposium on Circuits and Systems, 2005
We address the problem of unequal error protection (UEP) for MPEG-2/H.263 video over a wireless packet-erasure channel. Unequal amounts of protection are allocated to the different frames of a group-of-pictures (GOP) to provide a graceful degradation of video quality as packet loss rate varies.
