Serial Progressive Hierarchical Turbo Codes

2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011
Future radio technologies are expected to deliver ever higher bit rates and a wider range of data applications to an increasing number of subscribers. Flexible and high performance unequal error protection techniques are necessary for better application level perceived quality with lower data rates. In this paper, we present a new generalized mechanism

Predictable and Progressive Testing of Multithreaded Code

IEEE Software, 2011
The Chess (Checker for System Software) testing tool repeatedly executes a multithreaded program while guaranteeing predictable and deterministic scheduling and progressively exploring more schedules to uncover errors quickly.

Parallel progressive hierarchical turbo codes

2011 IEEE 7th International Conference on Wireless and Mobile Computing, Networking and Communications (WiMob), 2011
This paper proposes a modified parallel turbo structure based on embedding the unequal error protection concepts in parallel concatenated convolutional codes. These concepts may be required for compressed data packets transmission whose sensitivities to channel errors are not uniformly distributed.

Progressive coding of textured 3D models

Proceedings. IEEE International Conference on Multimedia and Expo, 2003
Due to the rapid development of computer and information technology, 3D modeling and rendering capabilities are becoming increasingly important in many applications, including industrial design, architecture, CAD/CAM, video games, and medical imaging. Since 3D mesh models often have the huge amount of the data, it is time-consuming to retrieve from a ...

Recent progress on perceptual video coding

2011 Visual Communications and Image Processing (VCIP), 2011
The purpose of this technical demonstration is to show how the compressed video quality can be improved by taking the characteristics of human visual system into account in the rate distortion optimization and rate control processes of a video encoder.

Progressive Coding for Hyperspectral Signature Characterization

2006
Spectral signature coding is an effective means of characterizing spectral features. This paper develops a rather different encoding concept, called progressive signature coding (PSC), which encodes a signature in a hierarchical manner. More specifically, it progressively encodes a spectral signature in multiple stages; each of these stages captures ...

Faster Progressive Wavelet Coding of Images

2008 International Conference on Computer Science and Software Engineering, 2008
Progressive wavelet coding of Images (PWC) is a simple and efficient image coding algorithm. It is comparable to the state-of-the-art SPIHT. It is based only on two concepts: (1) data-independent reordering and blocking, and (2) low-complexity independent encoding of each block via adaptive run-length/Rice coding of the bit planes. Therefore PWC allows

Analysis of coding risks in progressive transmission

Signal Processing: Image Communication, 2012
In progressive image transmission, there exist some risks which may appear during the processing. A first class of risks is the diminishing coding performance when the occurrence of insignificant coefficients at each transmission time is a small-probability event.

Sample-guided progressive image coding

Proceedings. Fourteenth International Conference on Pattern Recognition (Cat. No.98EX170), 2002
We introduce a low-level image representation using local orientation on a steerable pyramid. Its performance is demonstrated for a progressive image coder which transmits and reconstructs parts of an image guided by their similarity to a given sample image.
