Compressed images are often understood as static and indivisible objects. With the advent of scalable compression schemes including JPEG2000 and some modes of the JPEG standard, compressed images may be usefully accessed at reduced quality, resolution, or in selected spatial regions. Nevertheless, the original image remains unchanged. In this paper we are concerned with interactively editing sc...

In this thesis, an unequal error protection scheme for transmitting JPEG2000 images over wireless channel is investigated. The rapid growth of wireless communication has resulted in a demand for robust transmission of compressed images over wireless networks. The challenge of robust transmission is to protect the compressed image data against the impairments of the radio channel, in such a way ...

t Abstract.Thenewembeddingmethodofannotationsintorasterimagesispresentedinthearticle.Themethod combines the principles of watermarking and steganography. Using the method proposed it is possible to attach the information to the raster image and bind it to a specified object or region of the image. The JPEG2000 raster images coding standard is used as base to realize the embedding and extracting...

Every digital image has some spatial regions that are more important in some sense than others are. To provide higher reconstruction quality for the important region, Region of Interest (ROI) based compression methods are developed. In image compression, ROI coding allows to recover the ROI earlier than the rest of the image. JPEG2000 is an international standard for still image compression and...

Current gene-expression microarrays carry enormous amounts of information. Compression is necessary for efficient distribution and storage. This paper examines JPEG2000 compression of cDNA microarray images and addresses the accuracy of classification and feature selection based on decompressed images. Among other options, we choose JPEG2000 because it is the latest international standard for i...

Classification trade off in the JPEG2000 framework G. F. Fahmy and S. Panchanathan, Fellow IEEE Visual Computing and Communications Laboratory Research Center for Ubiquitous Computing (CubiC) Department of Computer Science and Engineering Arizona State University Email: {fahmy, [email protected]} Abstract In this paper, we propose a novel design for a lifting based wavelet system that achieves the ...

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 image. JPEG2000 is a wavelet-based coding system that is supported in the Digital Imaging and Communications in Medic...

In this paper an empirical evaluation of the lossy compression properties of the JPEG2000 standard for watermarking purposes is performed. The JPEG2000 standard is used as a basic tool for determining both how and where the embedded watermark should be placed in the image. The original image is slightly modified in order to generate a similar image (indistinguishable by the observer), and the m...

This document is intended for people who want to “be aware” of some of the mechanisms underlying the JPEG2000 image compression standard [2]. While writing this tutorial my objective was to give to the reader the feeling of what goes on when compressing images with JPEG2000 . Hence, this tutorial should be regarded as introductory material which requires further reading to reach a deeper unders...
