PARSEC is a popular benchmark suite designed to facilitate the study of CMPs. It is composed of 13 parallel applications, each with an input set intended for native execution, as well as three reduced-size simulation input sets. Each benchmark also demarcates a Region of Interest (ROI) that indicates the parallel code in the application. The PARSEC developers state that users should model only ...

This paper details work undertaken on the application of an algorithm for visual attention (VA) to region of interest (ROI) coding in JPEG 2000 (JP2K). In this way, an ‘‘interest ordered’’ progressive bit-stream is produced where the regions highlighted by the VA algorithm are presented first in bit-stream. The paper briefly outlines the terminology used in JP2K, the packet structure of the bit...

Three-dimensional wavelet coding of volumetric medical images provides better coding performance compared to corresponding 2D methods by exploiting the inter-slice correlation that exists in such data. It introduces however latencies when it comes to transmitting specific parts of the volume. This paper presents an extension to 3DSPlHT which allows 3D Region of Interest (ROI) coding. ROI coding...

In this study thermal imaging was used to monitor respiration rate in a noncontact manner. The main focus was to investigate the shape of a region under the nose (called the region of interest, ROI) and the characterisation of this region by a representative feature to produce a respiration signal from which respiration rate was obtained. It was demonstrated that the respiration signal from a r...

The segmentation algorithms vary for the types of medical images such as MRI, CT, US, etc.The current study work can further be extended to develop a GUI tool based approach for separating the ROI. Additionally, a new technique of separating ROI form the original image that will be applicable for all type of medical images can be evolved. Separated ROI can be stored with xmin, xmax, ymin and ym...

Simulation modeling and analysis requires an investment in human resources and software. And the rewards from using simulation are significant. Many companies fine tune their operations and reduce waste using simulation. But in the end, every time modeling and analysis are performed, a decision has to be made whether the simulation is “worth doing” (Waite 1999). In this paper we will enumerate ...

Region-of-Interest (ROI) tomography aims at reconstructing a region of interest C inside a body using only x-ray projections intersecting C with the goal to reduce overall radiation exposure when only a small specific region of the body needs to be examined. We consider x-ray acquisition from sources located on a smooth curve Γ in R3 verifying classical Tuy’s condition. In this situation, the n...

la reine morte  fut écrite par montherlant en 1942. elle met en scène une reprise d'un drame historique intitulé «régner après sa mort» de l'auteur espagnol luis vélez de guevara (1579-1644). beaucoup plus différente en détail, la pièce de montherlant comprend les conflits des protagonistes, à savoir ferrante le roi du portugal, don pedro son fils et sa belle-fille inès de castro. elle aboutit ...

introduction: in islamic countries in the month of holy ramadan many muslims based on their religious legislation refuse fluid intake during the fasting time though instructed to drink after injection of tc-99m methylene-diphosphonates [tc-99m mdp] used for skeletal scintigraphy. we aimed to establish whether fluid restriction in tc-99m mdp skeletal scintigraphy has an impact on its quality. me...

UNLABELLED Oxygen extraction fraction (OEF) is a key predictor of stroke recurrence in patients with symptomatic major cerebral arterial occlusive disease. The purpose of the present study was to compare central benzodiazepine receptor binding potential (BRBP) and cerebral blood flow (CBF) images on SPECT with OEF images on PET in patients with chronic unilateral middle cerebral artery (MCA) or...
