Energy-Efficient Transmission of Wavelet-Based Images in Wireless Sensor Networks

Vincent , Lecuire; Cristian , Duran-Faundez; Nicolas , Krommenacker

2007 EURASIP Journal on Image and Video Processing

We propose a self-adaptive image transmission scheme driven by energy efficiency considerations in order to be suitable for wireless sensor networks. It is based on wavelet image transform and semireliable transmission to achieve energy conservation. Wavelet image transform provides data...

Video Summarization Based on Camera Motion and a Subjective Evaluation Method

M. , Guironnet; D. , Pellerin; N. , Guyader; P. , Ladret

2007 EURASIP Journal on Image and Video Processing

We propose an original method of video summarization based on camera motion. It consists in selecting frames according to the succession and the magnitude of camera motions. The method is based on rules to avoid temporal redundancy between the selected frames. We also develop a new subjective...

Telescopic Vector Composition and Polar Accumulated Motion Residuals for Feature Extraction in Arabic Sign Language Recognition

T. , Shanableh; K. , Assaleh

2007 EURASIP Journal on Image and Video Processing

This work introduces two novel approaches for feature extraction applied to video-based Arabic sign language recognition, namely, motion representation through motion estimation and motion representation through motion residuals. In the former, motion estimation is used to compute the motion...

Costs and Advantages of Object-Based Image Coding with Shape-Adaptive Wavelet Transform

Marco , Cagnazzo; Sara , Parrilli; Giovanni , Poggi; Luisa , Verdoliva

2007 EURASIP Journal on Image and Video Processing

Object-based image coding is drawing a great attention for the many opportunities it offers to high-level applications. In terms of rate-distortion performance, however, its value is still uncertain, because the gains provided by an accurate image segmentation are balanced by the inefficiency of...

Image Resolution Enhancement via Data-Driven Parametric Models in the Wavelet Space

Xin , Li

2007 EURASIP Journal on Image and Video Processing

We present a data-driven, project-based algorithm which enhances image resolution by extrapolating high-band wavelet coefficients. High-resolution images are reconstructed by alternating the projections onto two constraint sets: the observation constraint defined by the given low-resolution image...

View Influence Analysis and Optimization for Multiview Face Recognition

Won-Sook , Lee; Kyung-Ah , Sohn

2007 EURASIP Journal on Image and Video Processing

We present a novel method to recognize a multiview face (i.e., to recognize a face under different views) through optimization of multiple single-view face recognitions. Many current face descriptors show quite satisfactory results to recognize identity of people with given limited view...

Real-Time 3D Face Acquisition Using Reconfigurable Hybrid Architecture

Johel , Mitéran; Jean-Philippe , Zimmer; Michel , Paindavoine; Julien , Dubois

2007 EURASIP Journal on Image and Video Processing

Acquiring 3D data of human face is a general problem which can be applied in face recognition, virtual reality, and many other applications. It can be solved using stereovision. This technique consists in acquiring data in three dimensions from two cameras. The aim is to implement an algorithmic...

Scalable Multiple-Description Image Coding Based on Embedded Quantization

Augustin I., Gavrilescu; Fabio , Verdicchio; Adrian , Munteanu; Ingrid , Moerman; Jan , Cornelis; Peter , Schelkens

2007 EURASIP Journal on Image and Video Processing

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 wavelet transform with the robustness and...

JPEG2000 Compatible Lossless Coding of Floating-Point Data

Bryan E., Usevitch

2007 EURASIP Journal on Image and Video Processing

Many scientific applications require that image data be stored in floating-point format due to the large dynamic range of the data. These applications pose a problem if the data needs to be compressed since modern image compression standards, such as JPEG2000, are only defined to operate on...

Localized versus Locality-Preserving Subspace Projections for Face Recognition

Iulian B., Ciocoiu; Hariton N., Costin

2007 EURASIP Journal on Image and Video Processing

Three different localized representation methods and a manifold learning approach to face recognition are compared in terms of recognition accuracy. The techniques under investigation are (a) local nonnegative matrix factorization (LNMF); (b) independent component analysis (ICA); (c) NMF with...
