    سند علمی۲۰۱۱Computer Vision and Image UnderstandingJoan Bartrina-Rapesta, Joan Serra-Sagristà, Francesc Aulí Llinàs

    Region Of Interest (ROI) coding is a prominent feature of some image coding systems aimed to prioritize specific areas of the image through the construction of a codestream that, decoded at increasing bit-rates, recovers the ROI first and with higher quality than the rest of the

    One interesting feature of the new JPEG2000 image coding standard is support of region of interest (ROI) coding using the maximum shift (Maxshift) method, which allows for arbitrarily shaped ROI image compression without shape coding or explicitly transmitting any shape informati

    Region of interest (ROI) coding is one of the innovative functionalities supported by JPEG2000. It enables a non-uniform distribution of the available bit budget (i.e. image quality) between a selected region (ROI) and the rest of the image (background). This is achieved by appro

    In this paper, we investigate region-based embedded wavelet compression methods and introduce region-based extensions of the Set Partitioning In Hierarchical Trees (SPIHT) and the Set Partitioning Embedded bloCK (SPECK) coding algorithms applied to the breast region of digital ma

  • Efficient rate control technique for JPEG2000 image coding using priority scanning

    سند علمی۲۰۰۳ICMEYick Ming Yeung, Oscar C. Au, Andy Chang

    Most of the computation and memory usage of the post-compression rate-distortion (PCRD) optimization scheme in JPEG2000 are redundant. In this paper, we propose a novel rate control scheme using priority scanning (PS) to address the problem. By encoding the truncation points in a
