This paper investigates the drifting problem in Progressive Fine Granularity Scalable (PFGS) video coding, which arises from the fact that high quality references are used to predict the enhancement layer. Due to the unique property of the PFGS scheme, this paper first analyzes the occurrence and propagation of the drifting errors in details. As a result, an iterative model is established to si...

Hermitian codes belong to a powerful class of algebraic geometry codes, which allow to correct many independent errors. We show that Hermitian codes can correct many bursts of errors as well. Decoding of a Hermitian (N,K) code over q2 can be reduced to decoding of interleaved extended Reed-Solomon codes. Using this fact, we propose an efficient unique decoding algorithm correcting up to (N −K)/...

Errors in the generation of the inhibitory GABAergic interneurons of the cerebral cortex and hippocampus have variable consequences. Studies of the molecular pathways of interneuron development reveal genes that are associated with human epilepsies. Animal models of gene variants exhibit seizures and abnormal electroencephalographic activity, providing unique models for discovering better treat...

Unlike the space of received words generated by substitution errors, the space of received words generated by insertion errors is infinite. Given an arbitrary code, it is possible for there to exist an infinite number of received words that are unique to a particular codeword. This work explores the extent to which an arbitrary insertion-correcting code can take advantage of this fact. Such que...

In ATM networks cell loss or channel errors can cause data to be dropped in the channel. When digital video is transmitted over these networks one must be able to reconstruct the missing data so that the impact of these errors is minimized. In this paper we describe a Bayesian approach to concealing these errors by post-processing the received data. In a prior paper [1], each frame in the seque...

Digital images generally suffer from two main sources of degradations. The first includes errors introduced in imaging, such as blurring due to optical aberrations and sensor noise. The second includes errors introduced during the processing. One particular example is the quantization noise arising from lossy compression. While image restoration is concerned with the recovery of the object from...

This study applied Human Factors Intervention Matrix (HFIX) framework and Analytic Hierarchy Process (AHP) to develop human errors intervention strategy. Our AHP questionnaire,designed based on the 31 incident scenarios that were taken place between 2009 and 2011 and included 72 safety recommendations to reduce specific human errors, was distributed to commercial airlines related personnel and ...

Linking individuals across historical datasets relies on information such as name and age that is both non-unique and prone to enumeration and transcription errors. These errors make it impossible to find the correct match with certainty. We suggest a fully automated method for linking historical datasets that enables researchers to create samples that minimize type I (false positives) and type...

The Scalar Triangulation and Ranging (STAR) method, which is based upon the unique properties of magnetic gradient contraction, is a high real-time ferromagnetic target localization method. Only one measurement point is required in the STAR method and it is not sensitive to changes in sensing platform orientation. However, the localization accuracy of the method is limited by the asphericity er...

the most important and practical phase of analyzing the linguistic errors of second language learners is to find the solutions to decrease these errors. to that end, the present study examined translation strategy to decrease the number of grammatical and lexical errors of chinese language learners learning persian. twelve chinese language learners were asked to write a text in two stages. firs...
