Intelligent scalable image watermarking robust against progressive DWT-based compression using genetic algorithms
Image watermarking refers to the process of embedding an authentication message, called watermark, into the host image to uniquely identify the ownership. In this paper a novel, intelligent, scalable, robust wavelet-based watermarking approach is proposed. The proposed approach employs a genetic algorithm to find nearly optimal positions to insert watermark. The embedding positions coded as chr...
متن کاملTowards Scalable and High Performance I/O Virtualization - A Case Study
I/O Virtualization provides a convenient way of device sharing among guest domains in a virtualized platform (e.g. Xen). However, with the ever-increasing number and variety of devices, the current model of a centralized driver domain is in question. For example, any optimization in the centralized driver domain for a particular kind of device may not satisfy the conflicting needs of other devi...
متن کاملModular Scalable I/O
We describe design issues for scalable I/O systems. I/O system modularity is the central issue. We identify the new information and algorithms responsible for high performance in scalable I/O. We show how to assign them to the parts of a scalable computer system so the result is modular. We built a modular I/O system and it is commercially available. We describe its design and performance bench...
متن کاملSelf-Virtualized I/O: High Performance, Scalable I/O Virtualization in Multi-core Systems
Virtualizing I/O subsystems and peripheral devices is an integral part of system virtualization. This paper advocates the notion of self-virtualized I/O (S-VIO). Specifically, it proposes a hypervisor-level abstraction that permits guest virtual machines to efficiently exploit the multi-core nature of futureion that permits guest virtual machines to efficiently exploit the multi-core nature of ...
متن کاملOperating System Support for High-performance Parallel I/o Systems Scalable I/o Initiative Working Paper No. 4 Operating Systems Working Group of the Scalable I/o Initiative
This document describes the operating system support component in the Scalable I/O Initiative. Our eeorts cover three critical areas of scalable, parallel I/O for high-performance multicomputers: networking, memory management, and le and object store. We are lever-aging oo ongoing research results in these three areas. Our main eeorts in the scalable I/O initiative will be directed towards hard...
