Motion‐Vector Refinement for Video Error Concealment Using Downhill Simplex Approach

open access: yesETRI Journal, 2018
In error‐prone wireless environments, it is difficult to realize video coding systems that are robust to various types of data loss. In this paper, a novel motion‐vector refinement approach is presented for video error concealment. A traditional boundary‐

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Motion field interpolation for temporal error concealment

open access: yes, 2000
When transmitted over practical communication channels, compressed video can suffer severe degradation. One approach to combat the effect of channel errors is error concealment.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Joint forward backward error concealment of redundantly coded video

open access: yes, 2010
Error concealment at the video decoder is to recover erroneous picture region based on correctly decoded region in the same frame or the neighboring frames.

A Novel Still Image Error Concealment Using Fragile Watermarking in Wireless Image , Transmission and Packet-Switched Networks

open access: yesInternational Journal of Information and Communication Technology Research, 2009
In this paper, we propose a new error concealment method for covering up the high packet losses of an original image after its transmission through an error-prone channel.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Video Error Correction Using Steganography

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
The transmission of any data is always subject to corruption due to errors, but video transmission, because of its real time nature must deal with these errors without retransmission of the corrupted data.
