Multiple description coding ghost imaging

Frontiers in Physics, 2023
Ghost imaging (GI) reveals its exceptional superiority over conventional cameras in a range of challenging scenarios such as weak illumination or special waveband. For high-performance GI, it is vital to obtain a sequence of high-fidelity bucket signals.

KSVD-Based Multiple Description Image Coding

IEEE Access, 2019
In this paper, we present a new multiple description coding scheme, which is based on a sparse dictionary training method called K singular value decomposition (KSVD).

Scalable Multiple-Description Image Coding Based on Embedded Quantization [PDF]

EURASIP Journal on Image and Video Processing, 2007
Scalable multiple-description (MD) coding allows for fine-grain rate adaptation as well as robust coding of the input source. In this paper, we present a new approach for scalable MD coding of images, which couples the multiresolution nature of the ...

Robust Baseband Compression Against Congestion in Packet-Based Fronthaul Networks Using Multiple Description Coding [PDF]

Entropy, 2019
In modern implementations of Cloud Radio Access Network (C-RAN), the fronthaul transport network will often be packet-based and it will have a multi-hop architecture built with general-purpose switches using network function virtualization (NFV) and ...

Multiple Description Coding of Discrete Ergodic Sources [PDF]

2009 47th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2009
We investigate the problem of Multiple Description (MD) coding of discrete ergodic processes. We introduce the notion of MD stationary coding, and characterize its relationship to the conventional block MD coding. In stationary coding, in addition to the

Multiple Description Coding with Side Information: Practical Scheme and Iterative Decoding [PDF]

EURASIP Journal on Advances in Signal Processing, 2009
Multiple description coding (MDC) with side information (SI) at the receiver is particularly relevant for robust transmission in sensor networks where correlated data is being transmitted to a common receiver, as well as for robust video compression. The

Polar Codes for Multiple Descriptions [PDF]

IEEE Transactions on Information Theory, 2014
A polar coding scheme is proposed for the multiple description coding (MDC) problem and is shown to be able to achieve a certain rate pair on the dominant line of the achievable rate region determined by El Gamal and Cover. This scheme is an adaptation of the one developed by ŗasoglu et al. for the multiple access channel (MAC) to the MDC setting.

Multiple description wavelet based image coding [PDF]

IEEE Transactions on Image Processing, 2000
We consider the problem of coding images for transmission over error-prone channels. The impairments we target are transient channel shutdowns, as would occur in a packet network when a packet is lost, or in a wireless system during a deep fade: when data is delivered it is assumed to be error-free, but some of the data may never reach the receiver ...

Repair Rates for Multiple Descriptions on Distributed Storage

Entropy, 2022
In a traditional distributed storage system, a source can be restored perfectly when a certain subset of servers is contacted. The coding is independent of the contents of the source.

Standard-Compliant Multiple Description Video Coding over Packet Loss Network

EURASIP Journal on Advances in Signal Processing, 2010
An effective scheme of multiple description video coding is proposed for transmission over packet loss network. Using priority encoding transmission, we attempt to overcome the limitation of specific scalable video codec and apply FEC-based multiple ...
