    Vector Lifting Schemes for Stereo Image Coding

    International audienceMany research efforts have been devoted to the improvement of stereo image coding techniques for storage or transmission. In this paper, we are mainly interested in lossyto- lossless coding schemes for stereo images allowing progressive reconstruction. The most commonly used approaches for stereo compression are based on disparity compensation techniques. The basic principle involved in this technique first consists of estimating the disparity map. Then, one image is considered as a reference and the other is predicted in order to generate a residual image. In this work, we propose a novel approach, based on Vector Lifting Schemes (VLS), which offers the advantage of generating two compact multiresolution representations of the left and the right views. We present two versions of this new scheme. A theoretical analysis of the performance of the considered VLS is also conducted. Experimental results indicate a significant improvement using the proposed structures compared with conventional methods

    The 1995 Science Information Management and Data Compression Workshop

    This document is the proceedings from the 'Science Information Management and Data Compression Workshop,' which was held on October 26-27, 1995, at the NASA Goddard Space Flight Center, Greenbelt, Maryland. The Workshop explored promising computational approaches for handling the collection, ingestion, archival, and retrieval of large quantities of data in future Earth and space science missions. It consisted of fourteen presentations covering a range of information management and data compression approaches that are being or have been integrated into actual or prototypical Earth or space science data information systems, or that hold promise for such an application. The Workshop was organized by James C. Tilton and Robert F. Cromp of the NASA Goddard Space Flight Center

    The IMAGE-2006 Mosaic Project

    This report details the data ingestion, data organisation, and main processing steps adopted for generating the IMAGE2006 mosaic products. Chapter 1 describes the received data and the way it has been ingested and organised. Chapter 2 presents a detailed analysis of the footprints of the received imagery. Chapter 3 details the procedure used for cloud detection. Relative geometric and radiometric accuracy is studied in Chap. 4. The generation of a cloud mask is indeed fundamental for the generation of a mosaic minimising cloud cover. The mosaicing methodology is presented in Chap.5 The produced mosaics are described in Chap.6.JRC.DDG.H.6-Spatial data infrastructure

    Handbook of Vascular Biometrics

    Get PDF
    This open access handbook provides the first comprehensive overview of biometrics exploiting the shape of human blood vessels for biometric recognition, i.e. vascular biometrics, including finger vein recognition, hand/palm vein recognition, retina recognition, and sclera recognition. After an introductory chapter summarizing the state of the art in and availability of commercial systems and open datasets/open source software, individual chapters focus on specific aspects of one of the biometric modalities, including questions of usability, security, and privacy. The book features contributions from both academia and major industrial manufacturers
